Operation Optimization Strategies for Power System Considering High Wind Power Permeability

Aiming at the problem of intermittent and fluctuating wind power generation that leads to the difficulty of real-time power balancing in system operation, this paper proposes a power system operation optimization strategy compatible with Battery Energy Storage System (BESS) and Demand Response (DR). Firstly, a power system framework for a high percentage of wind power access is proposed, and the imbalance problem between the supply and demand sides is reviewed. Secondly, the basic principles of BESS and DR models with their operational constraints are introduced. And then, typical scenarios are selected based on the real-time data from the supply and demand side using the K-means-DBI-based clustering method. Finally, three operation strategies are designed by the principle of single variables and are applied in different typical scenarios for simulation and analysis. The results show that the proposed strategies can effectively reduce the operation cost of the power system while effectively solving the imbalance problem.
