For making object of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The present invention proposes a kind of simple and realize the demand control system that cost is low, with intelligent electric meter novel, that can carry out in this locality demand response, and needn't carry out electricity usage control by the opertaing device of Utilities Electric Co. is long-range.
Fig. 2 is the structural representation with the intelligent electric meter of local demand response in one embodiment of the invention.This intelligent electric meter comprises: the first communication unit, CPU (central processing unit), signal acquisition process unit, user interface, digital output unit.
Wherein, the first communication unit, for receive electric power message from outside, offers described CPU (central processing unit).Generally, the electric power message that the first communication unit receives is sent by the opertaing device of Utilities Electric Co., for the electricity consumption situation of the whole electric system of simple instruction.
Described CPU (central processing unit), for configuration needs response policy, and searches described demand response strategy according to described electric power message, generates corresponding control command restriction or the electricity usage of recovery load.
In one embodiment of the invention, signal acquisition process unit is for gathering the electrical quantity in order to determine power demand.Correspondingly, described CPU (central processing unit) is further used for: described power demand and the restriction thresholding setting in advance and recovery thresholding are compared to the power demand state that obtains, and search described demand response strategy according to described electric power message and power demand state, determine corresponding control command.In the time of specific implementation, power demand can be calculated by signal acquisition process unit, and signal acquisition process unit now adopts DSP to realize.Certainly, simple simulating signal extraction and A/D conversion also can only be carried out in signal acquisition process unit, and the electrical quantity collecting is offered to CPU (central processing unit), calculate power demand by CPU (central processing unit).The specific implementation that it may be noted that signal acquisition process unit can, with reference to prior art, repeat no more herein.
In another embodiment, CPU (central processing unit) is further used for: detect the load electricity consumption situation of one or more load, search described demand response strategy according to described electric power message and described load electricity consumption situation, determine corresponding control command; Whether the electricity usage that wherein, described load electricity consumption situation is used to indicate described one or more load is restricted.
In another embodiment of the present invention, CPU (central processing unit) is further used for: described power demand and the restriction thresholding setting in advance and recovery thresholding are compared to the power demand state that obtains, detect the load electricity consumption situation of one or more load, search described demand response strategy according to described electric power message, described load electricity consumption situation and described power demand state, determine corresponding control command; Whether the electricity usage that wherein, described load electricity consumption situation is used to indicate described one or more load is restricted.
User interface not only shows electrical quantity, and shows the configuration of demand response strategy, makes user can this demand response strategy be arranged, be revised or upgrade.
The control command that numeral output unit is used for sending CPU (central processing unit) generation, to switchgear, according to control command, limits or recovers the electricity usage of its one or more load connecting by described switchgear.In Fig. 2, switchgear can be isolating switch (circuit breaker), converter (switch), relay (relay) etc., is arranged on subscriber's local, for controlling the electricity consumption of subscriber's local load.Particularly, digital output unit is by corresponding electric signal, the switching devices control that links.
In the system proposing in the present invention, the opertaing device of intelligent electric meter and Utilities Electric Co. communicates by letter to obtain simple electric power message.Further, the electrical quantitys such as the voltage and current of intelligent electric meter real time monitoring such as electric system, to determine power demand.Certainly, intelligent electric meter can also obtain current load electricity consumption situation, knows whether the electricity usage of one or more load is restricted.
In another embodiment, the control command that CPU (central processing unit) generates also can offer the switchgears such as isolating switch, converter, relay by the second communication unit shown in Fig. 3, to the electricity usage of load is limited or the control such as recovery.It may be noted that while adopting second communication unit switching devices to control, require switchgear can resolve the signal of communication that second communication unit sends.
Can find out, the core of intelligent electric meter provided by the invention is that its internal configurations has demand response strategy.In one embodiment of the invention, demand response strategy has two inputs, an output, as shown in Figure 4.This demand response strategy can be configured by user.These two inputs are respectively: (1) electric power message; (2) power demand of the power demand of systematic survey (power demand, PD) or prediction.Alternatively, in the time that intelligent electric meter has the function of predicted power demand, can adopt demand response strategy more flexibly.One is output as: digital output unit or second communication unit according to corresponding demand response strategy output control command to intelligent electric meter.
In the time of specific implementation, demand response strategy can only have an electric power message input, also can have electric power message, load electricity consumption situation, these three inputs of power demand state.
Further, in one embodiment of the invention, pre-configured demand response strategy records, is stored in intelligent electric meter with the form of demand response matrix.This demand response matrix has electric power message, load electricity consumption situation, these three dimensions of power demand state.
For this dimension of electric power message, in specific implementation of the present invention, the electric power message that the opertaing device of Utilities Electric Co. provides has 3 kinds of values:
(1) electric power message is logined (Utility message check-in), shows that now whole electric system reaches electric power peak demand, and Utilities Electric Co. wishes that user limits load in order to avoid risk appears in system.It may be noted that electric power message is logined can be considered as restriction of message.
(2) electric power message is published (Utility message check-out), shows the electric power peak demand mistake of whole electric system, and Utilities Electric Co. notifies user to return to normal running.Certainly, electric power message is published and can be considered as message recovery.
(3) unregulated power message, shows user behavior place one's entire reliance upon user's actual loading and self-demand, can not be subject to the impact of whole electric system.
For this dimension of load electricity consumption situation, the impact that one or more load can be brought according to function or load response is divided into N load group.Correspondingly, the value of load electricity consumption situation comprises N+1, respectively: electricity usage is unrestricted, 1 load group of restriction ..., N load group of restriction.
For example, be HVAC (HVAC by load partition, heating ventilation and air-condition), illumination, running time equipment, four load group of key equipment (in table 1) more flexibly, the value of load electricity consumption situation can be: electricity usage unrestricted (or full load), restriction HVAC, restriction illumination, restriction running time be equipment, restriction key equipment more flexibly.Taking restriction illumination as example, this value shows further restriction illumination on the basis of restriction HVAC, is expressed as intuitively two white circles in table 1; The restriction running time more flexibly this value of equipment show on the basis of restriction HVAC, illumination further restriction running time equipment more flexibly, in table 1, be expressed as intuitively three white circles.
Consider the significance level of different loads group, mainly alternative (significance level is 1, inessential) that can be using HVAC as load limitations, illumination also can pay attention to (significance level is 2).And then be running time equipment more flexibly; For key equipment, need to or reward in punishment, and these two aspect compromises that affect that restriction causes user's business are considered.The most unessential load group can limit last recovery or release at first, and the load group of most critical will finally be limited and discharge at first.In a specific implementation of the present invention, can use storehouse memory load group, as shown in Figure 5, restriction and release are just analogous to first to enter afterwards pushing on and popping in (FILO) storehouse.If use the current load electricity consumption situation of pointer mark, under the condition of full load, pointer=0; Under the condition of carrying at idling, pointer=N (N is load group number).
For this dimension of power demand state, need to consider be a typical commercial power bill not only for energy (or kilowatt/hour, i.e. kWh) charging, but also according to user with the contract of Utilities Electric Co. signing for peak demand charging.Arrive the peak demand of contract engagement at power demand before, will take load limitations.Just carry out load limitations if arrived the peak demand of contract engagement, often late.Therefore,, in demand response strategy provided by the invention, two demand response thresholdings are set for determining power demand state, as shown in Figure 6.
First be restriction thresholding (Pshield).When the power demand (PD) of measuring or predict is prescribed a time limit higher than limiting door; will take load limitations; since the peak demand of arranging in the contract that next peak demand may exceed and Utilities Electric Co. (utility) signs, and this fine or the electric power supply that conventionally can cause Utilities Electric Co. stop.
Next is to recover thresholding (Prelease).When dropping to, recovers under thresholding power demand, and former while pre-existing load limitations, be described restricted load restoration electric power supply.
Correspondingly, the value of power demand state can arrange according to power demand and the restriction setting in advance thresholding and the relation of recovering thresholding, comprises following 3 kinds: power demand be less than recover thresholding, power demand in recovering between thresholding and restriction thresholding, power demand is greater than restriction thresholding.It may be noted that the risk of being not only that above-mentioned two demand response thresholdings consider, also have the efficiency of system operation.
Further, contract peak demand (Pcontracted) can be set, if user in contract for peak demand charging, agreement arranges Pcontracted as agreed, otherwise can Pcontracted be set according to the full load demand of system (peak demand).Therefore,, in another specific implementation of the present invention, the value of power demand state has 4 kinds, comprising: PD be less than Prelease, PD be greater than Prelease and be less than Pshield, PD be greater than Pshield and be less than Pcontracted, PD is greater than Pcontracted.In addition, in a specific implementation, can be set to 95% of Pcontracted by Pshield, Prelease is set to 80% of Pcontracted.
Can find out, by the different value combinations of above-mentioned three dimensions, can obtain different conditions of demand (demand situation), when receiving that electric power message is logined, load electricity consumption situation is that electricity usage is unrestricted, and power demand state is that to be greater than restriction thresholding be exactly a kind of conditions of demand wherein to power demand.In the time that load group number is N, if power demand state has 3 kinds of values, total (N+1) * 3*3 kind conditions of demand; If power demand state has 4 kinds of values, there are (N+1) * 4*3 kind conditions of demand.Under every kind of conditions of demand, user can have 3 kinds of dissimilar respondent behaviors (response action): (1) is without respondent behavior; (2) the next load group in load group storehouse (as shown in Figure 5) is limited to (prerequisite is that still exist can confined load, and pointer is less than K); (3) a nearest confined load in load group storehouse (as shown in Figure 5) is discharged to (prerequisite is to have confined load, and pointer is greater than 1).In the load group storehouse shown in Fig. 5, the load group that significance level is K is placed in stack top, at the bottom of the load group that significance level is 1 is placed in stack.It may be noted that every kind of respondent behavior corresponding to conditions of demand is all configurable.
Through above-mentioned configuration, the example of the demand response matrix that intelligent electric meter has, in table 1, has 5*4*3=60 kind conditions of demand.This demand response matrix can be configured according to different conditions of demand in actual applications, for controlling the electricity usage of (i.e. restriction or recovery) one or more load group.
Table 1 demand response matrix example
If user does not consider to be configured for every kind of conditions of demand, also can adopt other forms of demand response matrix.For example, as a conservative option, can be forever without respondent behavior; Reward the option of tendency type as a Utilities Electric Co., in the time of the electric power message (being that electric power message is logined) occurring for limiting, always load is limited; As the option of a system operation tendency type, by limiting or discharging load group, systematic electricity demand is remained between the Prelease shown in Fig. 6 and these two thresholdings of Pshield.Certainly, can be configured the demand response matrix of self completely by user.
Fig. 8 is the method flow diagram of carrying out local demand response in one embodiment of the invention at intelligent electric meter, comprises the following steps.
Step 801: by user interface configuration needs response policy on intelligent electric meter.
Step 802: the value of determining the electric power message receiving.
Step 803: the value of determining load electricity consumption situation.Particularly, can be the information such as confined load group number or which load group are limited.
Step 804: intelligent electric meter compares the power demand calculating and Prelease and these two thresholdings of Pshield, thus determine the value of power demand state.It may be noted that intelligent electric meter can periodically calculate power demand, instead of calculate in the time carrying out local demand response.
Step 805: find corresponding conditions of demand according to the value of above-mentioned three dimensions from configured demand response strategy, determine pre-configured respondent behavior and generate accordingly control command, Fig. 7 is shown in the use signal of demand response strategy.
Step 806: intelligent electric meter sends to corresponding switchgear by described control command by digital output unit, for disconnecting (turn off) or connecting (turn on) described switchgear, thus restriction or the electricity usage that recovers the load group that this switchgear connects.
It may be noted that, in the local demand control with intelligent electric meter of the present invention, adopting the demand response strategy of matrix record is an embodiment, also can adopt other modes (such as expert system or artificial intelligence approach etc.) to realize demand response strategy.
Intelligent electric meter with demand response strategy provided by the invention can be applied to industry, building automation, house application etc.Embodiment from the above description can find out, intelligent electric meter provided by the invention at least has following one of them advantage:
(1) save cost.The invention provides local demand control, and do not adopt complicated long-range demand control system.It may be noted that long-range demand control system needs expensive equipment conventionally, complicated software, various communication facilities, telecommunication cable and general layout.
(2) be easy to realize.User only need configure local intelligent ammeter, just can obtain required demand control result.Do not need complicated IT structure in power consumption side.
(3) safeguard simply.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
