摘要:
高比例新能源接入对我国电网的调峰能力提出了更高要求,发展调峰辅助服务市场将成为促进新能源消纳利用的重要手段。梳理了我国现行调峰辅助服务的市场规则与交易流程,建立了基于火电机组单边报价的市场交易模型,该模型以火电调峰资源的调用成本最小化为目标,并考虑分时功率平衡、新能源弃电、火电爬坡等电网技术约束。为了充分发挥新能源机组的市场主体作用,设计了新能源与火电双边参与报价的市场机制及实施模式。并提出了以综合效益最大化为优化目标的双边交易模型,给出了不同市场主体效益评估方法。在实际算例中,分析单/双边交易机制下调峰市场交易结果、弃风弃光情况和不同主体收益,验证了模型的有效性。

Abstract:
The integration of large-scale renewable energy sources requires a higher level of peak regulation capability in China Power Grid, so rapid development of peak regulation auxiliary service market can serve as an important way to accommodate renewable energy production. The current market design and trading mechanism of peak regulation auxiliary service in China are investigated, and a market trading model based on the unilateral bidding of thermal units is developed. The objective of the model is to minimize the dispatching cost of thermal peak regulation resources, which satisfies a few operating constraints related with real-time power flow balance, renewable energy curtailment, and ramping limits of thermal units. Moreover, a new market mechanism and implementation mode is designed involving the bilateral bidding of both the renewable energy and thermal, which can motivate renewable energy producers to actively participate in the peak regulation market. At the same time, a bilateral trading model that maximizes the total social welfare is proposed, and the evaluation method of interest for different market entities is demonstrated. The case study is performed on a practical system, and the trading results of peak regulation market, renewable energy accommodation situation and interest of different entities under unilateral and bilateral trading mechanism are analyzed, so that the effectiveness of the model is validated.
Key words:  peak regulation auxiliary service  market mechanism  bilateral bidding  renewable energy accommodation
