Abstract
The invention belongs to the cross field of power system automation and computer digital simulation, and particularly relates to a radar chart index expression method for analysis and evaluation on power market. The method comprises the following steps: during the display of comprehensive analysis on multiple indices, extracting a set of indexes with high relevance of market evaluation, designing a radar chart, and intuitively monitoring the power market operation status in the process of power market operation or power market transaction simulation experiment.
Description
Technical field
The invention belongs to Automation of Electric Systems and Computer simulation crossing domain, be specifically related to a kind of radar chart index expression method of analysis and evaluation on power market.
Background technology
Electricity market: along with the affirmation of the strong functional power grid construction target of China.The electricity market process will further be deepened on the basis of existing three-class power market construction.The research of electricity market scheme and the operation state of actual market all need to carry out analysis and assessment.
Power market simulation: in recent years, in electricity market research, emulation mode had obtained increasing concern, and electricity market simulating system is the application system platform of application simulation technical research electricity market problem.Electricity market simulating system should comprise functions such as electricity market modeling, l-G simulation test operation control, test result analysis assessment, and testing and research and analyse for power market simulation provides technical support.
Analysis and evaluation: analysis and evaluation on power market is an important component part of power market simulation, is responsible for the historical data that the l-G simulation test subsystem is generated is carried out analyzing and processing.Calculate all kinds of indexs, make up appraisement system according to the market analysis evaluation theory, and utilize data warehouse and visualization technique, analysis result is showed, form all kinds of market analysis reports.
In Electricity Market Operation and the power market simulation research, a very important link is the operation present situation to electricity market, and perhaps the result of power market simulation transaction carries out analysis and evaluation.The index set of analysis and evaluation (evaluation index combination) is chosen with information translation pattern (obtain the method for evaluation information and to the information processing mode) and has been determined final evaluation effect and evaluation method.Evaluation index is concentrated, and single index can't comprehensively be described the running status in market, has only the relation between each index value of analysis-by-synthesis and numerical value could more comprehensively hold the test findings of current running status in market or the transaction of analysis power market simulation.
Summary of the invention
The objective of the invention is to overcome the deficiency of video data in the prior art, a kind of radar chart index expression method of analysis and evaluation on power market is provided.May further comprise the steps:
(1) determines the radar map analysis indexes;
The analysis indexes that radar map shows can be chosen in the analysis and evaluation index that native system calculates, and chooses mode and can choose 3 above indexs arbitrarily according to user's needs;
(2) carry out the power market simulation experiment;
Carry out the power market simulation experiment and at first will enter electricity market simulating system, set up the power market simulation model, the input experiment parameter starts the power market simulation experiment.Generate experimental result, the result is analyzed;
(3) computational analysis index;
1) market supply and demand: actual value: if (declare supply and demand ratio＞1.5,1.5, declare supply and demand ratio) full marks value: 1.5
2) market structure: actual value: if (Top4 index＜0.5,0.5,1-Top4 index) full marks value: 0.5
3) Market Constraint: actual value: do not have constraint and purchase electricity charge full marks value: have constraint to purchase the electricity charge and use
4) market competition: V=1-(average sale of electricity knock-down price/average sale of electricity quotation),
If V＞25%, score 100; Otherwise score=V/25%
5) market effective:
1. calculate between this group experiment each " wheel ": the coefficient R of " average sale of electricity knock-down price " and " capacity supply and demand ratio ";
2. the value of coefficient R own is between-1 to+1, and price should increase with supply and demand ratio and reduce, and R should bear, and R=-1 is the most effective;
3. full marks are 2, and actual value is 1-R, must be divided into (1-R)/2;
A[n] and B[n] two arrays, the related coefficient computing formula is:
(4) in the interface, show the radar map that comprises These parameters: on same plane, show These parameters;
(5) in the electricity market assessment, extract the mode of part evaluation index application radar map these indexs are concentrated displaying, according to the application mode of the graphical feedback marketing situation of each index distribution situation composition in the radar map.
The invention has the beneficial effects as follows:
Accurately: many index analysis market operation state has been avoided the one-sidedness of single index.The shape of radar map can reflect the balance between the desired value to a certain extent simultaneously;
Intuitively: situation and the numerical value that just can grasp many indexs from the shape of radar map rapidly.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is to use the operation interface of the inventive method.
Fig. 2 is the example that the result of calculation among the embodiment shows by radar map.
Embodiment
Set comprehensive is analyzed market supply and demand, structure, constraint, competition, 5 analysis indexes of validity in certain power market transaction experimental result.
Setting member " Huaneng Group Yi Min power plant " mock trading result with market in the market is that example is carried out index analysis calculating.
Index value is as follows:
Market supply and demand index=65;
Market structure index=100;
Market Constraint index=100;
Market competition index=20;
Market effective index=80;
Result of calculation by the radar map synthesis display as shown in Figure 2.
Show among the figure that the transaction results quality of balance is bad, illustrate that this city member market competition index in this mock trading is low, reflected that this this market of marketing activity member's quotation is lacked competitiveness.
Invention has been described according to specific exemplary embodiment herein.It will be conspicuous carrying out suitable replacement to one skilled in the art or revise under not departing from the scope of the present invention.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present invention, scope of the present invention is by appended claim definition.
