Abstract
The invention relates to an information model building method in the field of automation, in particular to a market structure public information model building method used for a multistage power market. A public information model carries forward the IEC62325-301 (International Electrotechnical Commission) standard and abides by the model extension principle of the IEC62325. The model building method includes two methods: 1, generating by directly importing from an XSD (xml schema definition) model file, namely directly importing from an existing XSD model file with data to form a market structure model, attribute values of the market structure market generated by directly importing from the XSD model file; and 2, newly generating. By the market structure public information model building method used for the multistage power market, standard establishment for mutual integration of market management software under a unified market or hierarchical market mode is realized, and by defining a standard format for information interaction, public data or interactive information which should have or a system has a standard mode have nothing to do with expression means of data inside an application system.
Description
Technical field
The present invention relates to a kind of information model construction method in power automation field, be specifically related to a kind of market structure common information model construction method for Multistage Electricity Market.
Background technology
The information model of electricity market is the business prototype of constructing flow of power transaction on the electrical network physical model, has super dimension, changeable, retrospective complex nature.Foundation is applicable to the common information model between different markets, is to realize market interconnected and resource optimization basis and key issue on a large scale.
The TC57 working group of International Electrotechnical Commission (IEC) is in May, 2012, issued the electricity market common information model, IEC62325-301 has concluded the Different Market Structure such as Europe, America, sets up to have formed a common information model that is applicable to Europe, America two class Power Market Systems.
IEC62325-301 has defined " market structure " common information model between a plurality of " sane level " formula market, and China has the level market structures such as country, zone, provinces and cities.Existing " market structure " common information model can't satisfy China's level market structure.
In addition, at present, also lack the market structure common information model construction method of a kind of being adapted to " multistage " electricity market, realize that the common information model of the market structure of " multistage " electricity market builds.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of market structure common information model construction method for Multistage Electricity Market, the method realizes being under united market or classification market mode the mutual integrated Criterion of each market management software, standard format by the definition information interaction makes these to have or system has common data or the interactive information of mode standard, and irrelevant in the expression way of application system inside with data.
The objective of the invention is to adopt following technical proposals to realize:
The invention provides a kind of market structure common information model construction method for Multistage Electricity Market, its improvements are, described model building method has two kinds:
(1) directly import generation from the XSD model file, namely directly import from existing XSD model file with data, form the market structure model, the property value of market structure model that directly imports generation from described XSD model file is constant;
(2) the brand-new generation, comprise the steps:
1) set up market information in the market structure model;
2) set up energy market information in the market structure model;
3) set up congestion revenue power market information in the market structure model;
4) set up elements of market information in the market structure model;
5) set up marketing plan information in the market structure model;
