Study of coordinating optimization for demand response participating in spinning reserve

With the development of smart demand response (DR) technology, it provide new ideas to utilize DR technologies to participate in spinning reserve of power system. Based on smart DR technologies, this paper presents a dispatching framework with DR participating in power system´s reserve in various time scales, and then a coordinated optimization model is proposed to determine how much capacity the DR should provide with considering of the cost of reserve. In this optimization model, the system cost includes both deterministic cost and risk cost, and the optimal total cost of DR participating in spinning reserve is the goal of the proposed coordinating optimization scheme. Finally, the feasibility and effectiveness of the proposed scheme is verified by numerical cases and simulation results.
