Description
Technical field
The invention belongs to the Power System and its Automation field, be specifically related to a kind of electricity market simulating system of the SOA of employing technology.
Background technology
SOA (Service-Oriented Architecture, Enterprise SOA) is a component model, and it connects the different function units (being called service) of application program by definition excellent interface and contract between these services.Interface is to adopt neutral mode to define, and it should be independent of hardware platform, operating system and the programming language of the service of realization.This makes the service be structured in various such systems to carry out alternately with a kind of unification and universal mode.This feature with neutral interface definition (not having to force to be tied in the specific realization) is called the loose coupling between the service.The benefit of loosely coupled system has 2 points, a bit is its dirigibility, and on the other hand, when the inner structure of each service of forming whole application program little by little changed with realization, it can exist.
Electricity market simulating system still is in an exploratory stage, demand will be along with the deeply and constantly variation of simulation study, in order to reduce the problem of isomerism, interoperability and changing requirement, analogue system platform application SOA technique construction has the application program service of following feature: loose couplings, location transparency and agreement are independent.
Electricity market simulating system support platform based on the application of SOA technology, the application deployment service is flexible during the function expansion, and reusability is good, when using, integrated other function can pass through service call resolution protocol typical problem, need not to be subjected to the technology of integrated application to realize the different restrictions and the restriction of platform, realized dirigibility, reusability, opening and the extensibility of electricity market simulating system, and the concurrency of l-G simulation test.
The main method of research electricity market has the theoretical research based on microeconomics, game theory and finance etc. at present, to the empirical analysis or the proof analysis of actual electricity market, based on agency's the economic simulation method of calculating, the experimental analogic method of experimental economics.
Based on microeconomics, game theory method mainly is to find the solution by setting up the electricity market mathematical model, adopts correlation theory to research and analyse to the every factor that influences market.For example study the bidding strategies problem of genco in the market, can adopt the game theory methods analyst to draw a set of strategies, and genco calculates optimal strategy to separately cost, income etc.
The empirical analysis of actual electricity market mainly is the historical data according to electricity market, perhaps investigates in actual market, draws the problem that electricity market exists by analysis.Because the singularity and the complicacy in real-time electric power market, above method is mainly used to study the theoretical case or the historical crash analysis of electricity market, and market analysis exists some limitation to real-time electric power.The construction design of electricity market should adapt with its feature, is difficult to come modeling with positive method and conventional microeconomics, game theoretic method.
If electricity market is carried out simulation study, can design according to the actual conditions of electricity market, can find the potential problems that electricity market may exist, can help us in more profound and wider scope, to go to seek the inherent law of electricity market.These problems will influence many important electricity market decision-makings, and the cost of market enforcement ex-post analysis is very high, and power market simulation just becomes requisite research method.Power market simulation can be provided with according to the actual conditions of electricity market, be adapted to the Analysis of Complex economic system, can check the feasibility of various electricity market rules, also can test, so power market simulation can be used as the research method of a kind of " discovery " system and announcement electricity market inherent law at some key issues and hypothesis.
The method of the simulation study of electricity market mainly is divided into based on agency's calculating economics emulation and experimental economics experiment.Based on agency's simulation method mainly is to act on behalf of genco by intelligent algorithm to carry out bidding strategies and select, then according to go out all kinds of problems that clearly result studies electricity market at every turn.The method of experimental economics experiment is the earliest by Vernon. and Smith proposes and is applied to the experiment of power industry, mainly be by building a unified market platform, experiment parameter and experimental situation are set, and are experimentized by relevant personnel, experimental then result studies.Experimental economics is the power market transaction actual conditions that go out of real simulation more, but are subject to disturb, and the result who draws does not often restrain, and can not carry out qualitative explanation to some factors; And Computer Simulation is very rational, although bigger with actual market situation difference, can clearly reflect the influence of each factor.
