Embodiment 1
A kind of micro-capacitance sensor spare capacity adjusting method that the application provides, is mainly used in sale of electricity side, and be mainly practically applicable to
Sale of electricity company has two kinds of powering modes of micro-capacitance sensor and public network, and user possesses low profile photovoltaic or wind power generating set distributed
Power supply, and can be to sale of electricity company foldback electricity, the electricity consumption electricity price and grid-connected electricity price of user are determined by sale of electricity company and can be in certain areas
Interior adjusting.
Fig. 1 is the flow chart of micro-capacitance sensor spare capacity adjusting method provided by the embodiments of the present application, referring to Fig. 1, this method
Include the following steps:
S101:Load is subjected to classifying importance.
Load classifying importance may include it is a variety of, such as importance load, secondary property load, non-secondary property load etc., at this
It is not limited in embodiment.The foundation of classifying importance is carried out to load is:Important load must assure that its power supply, Er Feichong
The load wanted can cut off power supply in power supply capacity deficiency.
S102:Based on classifying importance, the spare capacity that micro-capacitance sensor needs is calculated.
The spare capacity that micro-capacitance sensor needs depends mainly on the size of the size of network load, therefore according to the importance of load
Classification can calculate the spare capacity of micro-capacitance sensor needs using formula.
S103:Obtain the equipment status parameter in micro-capacitance sensor.
Passability can detect, the modes such as acquisition of information obtain in micro-capacitance sensor status attribute of equipment itself and operation and
Attribute under the states such as stand-by heat.

The spare capacity of offer.
S105:Spare capacity as needed and available spare capacity carry out certainly electricity consumption electricity price and grid-connected electricity price
It is dynamic to adjust.
The spare capacity needed is mainly derived from the load electricity consumption of user in power grid, it is possible to provide spare capacity by power grid
Distributed energy determine.When the spare capacity of needs is larger and the available spare capacity of power grid is smaller, micro-capacitance sensor is by nothing
Method carries out normal power supply in the case where public network stops power supply to load, when available spare capacity is more than the spare appearance needed
During amount, available spare capacity is remaining, causes electric company's power supply cost excessively high, energy loss.Adjust electricity consumption electricity price and simultaneously
The situation of load electricity consumption in power grid can be adjusted in net electricity price, so as to make the spare capacity of needs and available spare appearance
Amount keeps balance, while ensureing electricity consumption reliability, balances sale of electricity income.
S106:Based on the electricity consumption electricity price after the adjusting and grid-connected electricity price, the spare capacity of the micro-capacitance sensor is adjusted.
By the automatic adjustment to electricity consumption electricity price and grid-connected electricity price, user to be guided to change the electricity consumption of itself, so as to shadow
The spare capacity size that micro-capacitance sensor needs is rung, realizes the adjusting control to spare capacity.
It is possible it is a kind of in the case of, electricity consumption electricity price and grid-connected electricity price are promoted, the considerations of user can be for expense and reduce
The use of unnecessary load in family, reduces the electricity consumption in power grid, and increase possible power supply, is made certainly in electric power with reducing

The smaller spare capacity supplied can meet the needs of load.It, can be to therein negative when public network occurs stopping power supply
Lotus provides normal power supply, ensure that the reliability of micro-capacitance sensor power supply.Meanwhile under square one, it is relatively small provide it is standby
With capacity, the cost of power supply is reduced, and the electricity consumption for reducing user is spent, balance the income of user and sale of electricity company, it is real
Benign interaction is showed.
In the case of possible one kind, electricity consumption electricity price and grid-connected electricity price are reduced, the bootable user of relatively low expense, which increases, to be used
Electricity simultaneously reduces possible power generation, improves the electricity consumption in power grid, and reduce possible power generation, is ensureing customer power supply reliability
Meanwhile increase the income of electric company.Meanwhile be conducive to rationally utilize electric power resource.
Load is subjected to classifying importance first, and according to the classifying importance of load, calculates and accident occurs not in public network
In the case of powering, micro-capacitance sensor realizes the spare capacity that power supply needs.Equipment status parameter in micro-capacitance sensor calculates micro-
The spare capacity that power grid can provide.The size of spare capacity as needed and available spare capacity, to electricity consumption electricity price
It is automatically adjusted with grid-connected electricity price.Electricity consumption electricity price and grid-connected electricity price after adjusting, bootable user to itself electricity consumption into
Row is adjusted, and so as to which the spare capacity needed in power grid be adjusted, realizes the adjusting of micro-capacitance sensor spare capacity, ensures that user supplies
While the reliability of electricity, the income of sale of electricity company is balanced, while the spare capacity of offer is rationally provided, is conducive to electric power
The reasonable utilization of resource.
Optionally, spare capacity as needed and available spare capacity carry out electricity consumption electricity price and grid-connected electricity price
Automatic adjustment includes:
The spare capacity needed is more than available spare capacity, then increases electricity consumption electricity price and grid-connected electricity price.
The spare capacity needed is less than available spare capacity, then reduces electricity consumption electricity price and grid-connected electricity price.
When the spare capacity needed is larger, show that the load in power grid is larger, then increase the electricity consumption electricity price of user and grid-connected
Electricity price, guiding user lower the load of unnecessary electricity consumption, ensure the reliability of power supply.
When the spare capacity needed is smaller, show that available spare capacity has residue, then reduce the electricity consumption electricity price of user
With grid-connected electricity price, guiding user increases electricity consumption, the income of balance sale of electricity company.
Fig. 2 is spare capacity as needed provided by the embodiments of the present application and available spare capacity to electricity consumption electricity price
With the method flow diagram of grid-connected electricity price automatic adjustment, referring to Fig. 2, this method includes the following steps:
S201:Calculate the capacity tolerance of the spare capacity needed and available spare capacity.S202:Capacity tolerance is more than
Dead band value then increases electricity consumption electricity price and grid-connected electricity price.
S203:Capacity tolerance is less than dead band value, then reduces electricity consumption electricity price and grid-connected electricity price.
It should be noted that the dead band value is the deviation range of setting, imparting needs spare capacity and can provide spare appearance
