摘要:

高比例可再生能源并网使得电力系统安全、稳定、经济运行面临着巨大挑战,需求响应作为一种重要调节手段在电力供需平衡中扮演着愈加重要的角色。然而,需求侧资源响应具有较大的不确定性,导致需求响应市场规模有限,经济驱动力不足。为有效引导需求侧提供高质量响应服务,设计了一种考虑响应率差异的交易机制,提出资源质量评估指标,基于“高质高价”原则制定动态奖惩规则。在该机制作用下,需求侧为规避低响应质量带来的经济风险,提出广义储能聚合商的形式,构建将高响应精度、高成本的狭义储能与低响应精度、低成本的虚拟储能相结合的广义储能运营决策模型,协同参与市场交易,并探讨改进机制对其运营决策的影响。基于美国PJM市场数据的算例表明,改进机制可为聚合商提供经济利益驱动,有效引导其主动提升响应率,为电网提供更加优质的服务,以实现双赢。

Abstract:

The integration of high proportion of renewable energy makes security, stability and economic operation of power system face great challenges. As an important adjustment method, demand response (DR) plays an increasingly important role in the balance of power supply and demand. However, the response of demand-side resources has great uncertainty, which leads to a limited demand side market and insufficient economic motivation. In order to effectively guide the demand side to provide high-quality response services, this paper designs a transaction mechanism considering the response rate difference, puts forward the evaluation index of resource quality, and formulates a dynamic reward and punishment mechanism based on the principle that “resource with high response rate has high reward price”. Under this mechanism, in order to avoid the economic risk caused by low response quality, the form of generalized energy storage aggregator (GESA) is proposed on the demand side, and the generalized energy storage operation decision model is constructed, which combines the narrow energy storage of “high response precision and high cost” with the virtual energy storage of “low response precision and low cost” to cooperatively participate in the market transaction. The influence of the improved mechanism on its operation decision is also discussed. The calculation example based on the US PJM market data shows that the improved mechanism can provide economic benefit motivation for aggregators, effectively guide them to actively improve the response rate, provide better service for the power grid, and achieve a win-win situation.
