Power market mechanism design method based on renewable energy and load response

Abstract

The invention discloses a day-ahead power market mechanism design method based on renewable energy randomness and load response. The method comprises the following steps: inputting prediction data andactual measurement data of historical output power of a renewable energy power station in a system; modeling a renewable energy power generation distribution model based on the truncated general distribution model; establishing a day-ahead clearing model of the electricity market and a controllable electric equipment model under an electricity seller; solving a distributed day-ahead market clearing model and a controllable electric equipment model under an electricity seller based on an alternating direction multiplier method; and outputting a planned output curve of the day-ahead conventional unit and the renewable energy power station and a load power curve of the controllable electric equipment model under the electricity seller. Compared with a traditional deterministic model containing renewable energy sources, the model of the invention has the advantages that the social cost can be greatly reduced, and the distributed day-ahead market clearing method based on the alternating direction multiplier method has good convergence and efficient calculation efficiency.

Description

Technical field [0001] The invention relates to the field of power market design, in particular to a power market mechanism design method based on renewable energy and load response. Background technique [0002] Today, China’s power market reform is gradually being carried out. The focus of power system reform is to establish a unified, open, and competitive power market system, give full play to the decisive role of the market in resource allocation, and form a relationship with power markets in Europe, the United States and other countries. The difference in the process is that the construction of China's power market is accompanied by new trends in the continuous development of renewable energy. Chinese research institutions have stated that by 2050, 60% of China's electricity will come from renewable energy. [0003] At present, many scholars at home and abroad focus on the research of the electricity market mechanism, and often ignore the influence of its randomness in the tr...

Problems solved by technology

However, in the traditional unified adjustment mode, trading institutions or dispatch centers need to use private information such as the user satisfaction function under the electricity retailer and the user's power consumption to solve the problem, which is difficult to carry out in field operations.
