Balanced optimization device based on electric power green evidence market joint clearing model

Abstract

The invention provides a balanced optimization device based on an electric power green certificate market joint clearing model, and the device is based on a computer system and a program, and executes the following technical design: according to the historical output data of renewable energy sources, extracting a renewable energy source output characteristic curve through clustering analysis and other algorithms; setting parameters such as weight indexes of power consumers, basic parameters of each market subject, probabilities of different scenes, unit output, load fluctuation and the like under a renewable energy source forehead system; performing linearization processing on the power-green certificate market joint clearing model to convert the power-green certificate market joint clearing model into a solvable mixed integer linear programming model; in a pre-established power-green certificate market combined clearing model, quotation parameters of a strategy quoter are initialized, and the power-green certificate market combined clearing model is solved through a diagonalization algorithm, so that an optimal value for balanced optimization in the model is obtained; comprising market clearing electricity price, bid-winning capacity of each market subject, an optimal quotation strategy of a strategy quoter and the like.

Description

technical field [0001] The invention belongs to the technical field of electric power trading systems and devices, and in particular relates to a balanced optimization device based on a joint clearing model of the electric power green certificate market. Background technique [0002] The reform of the power system was further deepened, and eight pilot provinces took the lead in building a spot market for electricity, which further improved the degree of openness of the electricity market. In the future, as the proportion of renewable energy power marketization gradually increases, the uncertainty, volatility, intermittency and green certificate market of renewable energy power will have a profound impact on the equilibrium results of the power market. Therefore, the study of renewable energy quotas The electricity market is of great significance under the background of the parallel system and the electricity spot market. At present, the electricity market model basically onl...

Problems solved by technology

In the future, as the proportion of renewable energy power marketization gradually increases, factors such as the uncertainty, volatility, intermittency of renewable energy power, and the green certificate market will have a profound impact on the equilibrium results of the power market. Therefore, research on renewable energy quotas The power market under the parallel background of the renewable energy quota system and the power spot market is of great significance. The current power market model basically only focuses on the electric energy market, and does not include the requirements of the renewable energy quota system for market players, the green certificate market, and the excess consumption market. Consider; most of the existing power market models simplify too many conditions, and do not fully consider the constraints of segmented quotations, power flow and phase angle constraints, renewable energy output and load fluctuations, and time-of-use quotations
