考虑多源互补特性的新能源打捆销售交易策略

Trading Strategy for Bundle Sales of Renewable Energy StationsConsidering Multi-source Complementary Characteristics

摘要:

随着新能源交易电量在电力市场的比例迅猛上升，为解决由于新能源出力波动性造成的中长期电力市场合同履约执行率的问题，提出了一种考虑多源互补的新能源场站打捆销售的电力市场交易策略。首先，设计了新能源场站与常规机组打捆销售的中长期交易框架，提出了通过集中式交易平台调整机组出力满足新能源合同签约电量的联盟交易方案;其次，以多源互补联盟交易模型收益最大为目标，构建了基于合作博弈的新能源场站打捆销售交易模型;最后，以四川某区域风电场的实际数据对所构建交易模型进行了仿真分析，对打捆销售联盟的交易电量和收益结果进行了讨论。仿真结果表明，多源互补合作交易的方式在提高参与主体收益的基础上还能满足电力市场的合同签约电量。

Abstract:

With the rapid increase of trading electricityof renewableenergy in electricity market, and in order to solve the problem of execution rate of medium and long-term electricity market contract performance due to the output fluctuation of renewable energy, an electricity market trading strategy for bundled sales of renewableenergy stations is proposed considering multi-source complementation. Firstly, a medium and long-term trading framework for bundled sales of renewable energy stations and conventional units is designed, and an alliance trading scheme is proposed to adjust the unit output to meet the contracted energy quantity of renewable energy contracts through a centralized trading platform. Secondly, aiming at the maximum revenue of multi-source complementary alliance trading model, a bundled sales trading model for renewable energy stations based on cooperative game is constructed. Finally, the constructed trading model is simulated and analyzed with the actual data of wind farms in a certain region of Sichuan, and the results of trading volume and revenue of bundled sales alliance are discussed, which shows that the way of multi-source complementary cooperative trading can satisfy the contracted energy quantity in electricity market on the basis of improving the revenue of the participating entities.
