Research on multi-demand response resources involved in spinning reserve optimization for new power system

Abstract

In the future, the new power system dominated by high proportion of new energy will pose a new flexibility challenge to China's traditional reserve ancillary services market. In addition to power generation resources, user-side demand response resources can also provide reserve services. In the market environment, with the development of new market subject load aggregators, more small and medium-sized users' demand response resources can participate in system operation more effectively through the agent of load aggregators, especially in the spinning reserve market, and give full play to the value of demand response resources to improve system flexibility and economy. Based on the new model of small and medium users' demand response resource load aggregators participating in the spinning reserve market, and the generator set outage failure and the uncertainty when demand response resource provides reserve, This paper introduced the expected energy not supplied (EENS) reliability index ,and established the optimization model of multiple rotating reserve resources. On the premise of satisfying certain reliability, the model can minimize the reserve ancillary services market purchase cost and expected loss of low power. The example of IEEE30 node system shows that the model effectively coordinates the economy and reliability of the system.
