A Modeling Method of Electricity Market Membership Economic Model and Data Model

Abstract

The invention relates to an electricity market economic model modeling method adaptive to a plurality of investment subjects. The method comprises the following steps: (1) dividing an economic unit on a physical unit level; (2) designing an economic model structure of a market member; (3) designing a business data model structure; and (4) designing relationship between an electricity market transaction operation system interface and the business data model structure. After one physical unit is invested by a plurality of power plant market member subjects, multilevel and extensible electricity market economic models, such as a market member, a business department, the physical unit, the economic unit and the like, are established to adapt to the realization of the whole-process management of a relevant business data flow of the economic model in a plurality of business links, such as competitive price transaction, contract signing, electric quantity plan compiling, electric energy settlement and the like, in electricity market operation.

Description

technical field [0001] The invention relates to a modeling method in the field of electric power automation, in particular to a modeling method for a power market economic model adapting to multiple investment subjects. Background technique [0002] The economic model of the electricity market is the most important basic data for carrying out the transaction and operation of the electricity market, and it is the core model support structure for realizing the business. At present, the model level in the business carried out by power grid companies includes different types of model information such as market members, units, and physical units. When there are multiple investment entities, a new market member model is generally re-established through the division of physical units to achieve model changes. with extensions. However, with the expansion of business, a physical unit has been invested and constructed by multiple entities in some areas, and it needs to independently ...

Problems solved by technology

However, with the expansion of business, a physical unit has been invested and constructed by multiple entities in some areas, and it needs to independently participate in bidding transactions, contract signing, and energy settlement. The original market member model structure can no longer adapt; In addition, since the types of business units are extended to bidding, planning, settlement, statistics, etc., the model associations among multiple business units are not consistent, which brings difficulties to the underlying data associations throughout the transaction and operation of the electricity market. How to pass information The system meets business needs and brings great trouble
