An Optimal Scheduling Strategy of Spinning Reserve Considering Coordination Between Source and Load for Power System

Due to large-scale wind power integration, the operation and reserve of power system has been seriously affected. It is necessary to utilize other resources to replace conventional generators to provide reserve capacity for power system. Taking multiple types of reserve resources into account, an optimal scheduling strategy of spinning reserve considering coordination between source and load for power system is proposed. Firstly, according to the mode and operation constraints of reserve resources, the reserve models of conventional generators, wind farm and demand response are established. Secondly, with the objective function of minimizing the operation cost and reserve cost of power system, the optimal scheduling model of spinning reserve based on source load coordination is constructed. Finally, a case of 6-machine 30 bus system is carried out to prove that the economy of power system is improved obviously, and the effectiveness of the proposed optimal scheduling strategy is verified. Furthermore, the impact of wind farm and demand response reserve cost on the system spinning reserve capacity allocation is analyzed respectively, and it has a certain reference significance for reserve resource bidding mechanism of power system.
