Analysis of Residential Demand Response in Electricity Markets with Wind Generation

研究了2种类型的需求响应策略对含可再生能源电力市场的影响。考虑寡头垄断电力市场,利用经济学原理模拟电力市场交易,利用安全约束机组组合进行电价出清。选择分时电价、实时电价和尖峰电价作为基于价格的需求响应,以及3种紧急需求响应价格作为风电场景下基于激励的需求响应。然后建立了用户需求响应模型,考虑日前市场和实时市场2种情况下的约束,并提出联合求解算法。最后利用IEEE6节点系统进行仿真,分析了不同需求响应策略下机组的交易情况,说明了模型的有效性。

The effects of two types of demand response strategies on the electricity market with renewable energy are studied.Considering the oligopoly power market,the game theory model is used to simulate power market transactions,and the securityconstrained unit combination is used to clear the electricity price.Timeofuse electricity prices,realtime electricity prices,and peak electricity prices are selected as pricebased demand responses,and three types of emergency demand response prices are used as incentivebased demand responses with wind power.Then a user demand response model is established,considering the constraints of the dayahead market and the realtime market.Finally,the IEEE6 bus system is used to simulate the transaction situation of the unit under different demand response strategies,which illustrates the effectiveness of the model in this paper.
