Research on Reserve Capacity Optimization of Power System

The rapid development of renewable energy increases the uncertainty in power system and requires the provision of more reserve capacity to ensure the safe operation of the system, and the study of reserve capacity optimization with comprehensive consideration of system operation reliability and economy is of great significance. Based on the analysis of conventional units participating in the provision of reserve in power system, an optimal configuration method of flexible load and energy storage participating in system reserve is proposed, and a source-load-storage multi-type reserve system is constructed to improve the system reserve capacity. The power system reserve optimization model is established and the system reserve capacity constraint based on the chance constraint is set. Finally, the calculation results prove the superiority of the reserve optimization model.
