Embodiment

[0158] For a coupled system consisting of 1200MW thermal power, 300MW wind power, and 400MW photovoltaic on a 500kV grid-connected node, the user transmission and distribution price is 0.4774 yuan / kWh. In addition to the coupling system, there are two competing thermal power companies in the annual bilateral transaction market. Each party trades in segments during a typical day divided into 24 time periods. Since the marginal cost of renewable energy in the coupled system is approximately zero, relative to thermal power units in the coupled system, the power price increase parameter b of the coupled system 1 To make adjustments, the electricity price growth parameters of the coupling system are reduced through the proportion of thermal power installed capacity. The parameters of each power generation enterprise are shown in Table 1:

Abstract

The invention discloses a benefit evaluation method for a coupling system participating in annual bilateral transaction. The method comprises the steps: carrying out the actual analysis of an annual bilateral market, thereby obtaining a specific game scene of the coupling system, setting that the annual bilateral transaction market in which the coupling system participates comprises a power generation enterprise (including the coupling system) and a large user, carrying out transaction simulation in the typical days divided into the transaction periods by each market participant(annual contracts are regarded as contract accumulation of each typical day); constructing a coupling system annual bilateral transaction master-slave game model in combination with a coupling system electricity selling profit function and a large user cost optimization function; solving the model to obtain the specific income condition of the coupling system participating in the annual bilateral transaction; the problems of low renewable energy transaction electric quantity proportion and high peak regulation apportionment cost in current annual bilateral transaction are solved.

Description

technical field [0001] The invention belongs to the technical field of power market design, and in particular relates to a benefit evaluation method for coupling systems participating in annual bilateral transactions. Background technique [0002] Under the background of my country's "dual carbon target", the continuous and rapid growth of renewable energy installed capacity has become inevitable. In order to deal with the consumption problems brought about by the large-scale access of renewable energy in the power system, the National Development and Reform Commission and the National Energy Administration are vigorously promoting the construction of "multi-energy complementarity" in order to strengthen the two-way relationship between renewable energy and the power system. friendliness and increase the level of renewable energy consumption. The coordination and cooperation between multiple energy sources can not only effectively promote the optimal allocation of power res...
