Multi-area scale electric power and energy balance with high wind power penetration based STACKELBERG decision theory

Abstract

In order to coordinate the electric power and energy balance with the space scales and spatial scales among different level dispatching center, a leader-follower hierarchical decision model is proposed for taking advantage of the wind speed complementary characteristic of multi regional wind farms. With the STACKELBERG decision strategies, a coordination decision model of the electric power and energy balance is to combine the bottom-up feasibility tests with the top-down target optimizing. The follower layers would give a commitment to the leader layer, and the leader layer would optimize the follower layers commitments and get an optimized agreement for all followers. A dynamic programming optimization method is employed for calculating the entire system balance plan. The simulation results demonstrate that the proposed decision-making structure fits to large-scale power system hierarchical dispatching and satisfy the coordination of various dispatching demand in different levels.
