Real-Time Demand Response Theory Based on Load Regulation Capability Model

需求响应在协助维持电力系统稳定性、提高可再生能源消纳能力、降低电力系统峰谷差、延缓电网建设投资等方面发挥重要的作用,基于实时电价的实时需求响应更是把需求响应从实时性、最优性上推到了一个新的高度。从分析准实时电价存在问题出发,提出了实时电价的基本特征,从而提出一种新的需求响应形式:实时需求响应。具体算法上,以单设备潜力聚合法负荷调节能力模型为基础,建立完整的实时需求响应数学模型,明确其求解和效益评估过程,通过用例分析,不仅验证了实时需求响应模型的有效性,还验证了该模型适合实时电价的实时快速计算。

Demand response plays an important role in helping to maintain the stability of the power system,improve the consumption capacity of renewable energy,reduce the peak valley difference of the power system,and delay the construction investment of the power grid.The real-time demand response based on real-time price pushes the demand response to a new height from real-time and optimal.Based on the analysis of the existing problems of quasi real time price,this paper puts forward the basic characteristics of real-time price,and puts forward a new form of demand response:real-time demand response.In the specific algorithm,based on the load adjustment capacity model of single equipment potential aggregation method,a complete mathematical model of real-time demand re-sponse is established,and its solution and benefit evaluation process are clarified.The effectiveness of the real-time demand response model is verified by case analysis,and the model is proved to be suitable for fast real-time calculation for real-time price.
