Abstract:

Considering different types of power output characteristics and the complementarity and contradiction between them, a multiobjective optimal dispatching model is built for a power generation system that includes hydropower, thermal power, wind power, and an energy storage system. The proposed model is characterized by minimal system cost, minimal air pollution emission, and maximal clean energy utilization. A Monte Carlo simulation and a genetic algorithm are combined to validate the effectiveness of the proposed model using an improved 39-node system. Both the hydropower and energy storage system can fulfill their regulatory functions to the greatest extent in different situations, thus stabilizing the fluctuation of wind power, reducing air pollution emission and wind abandonment, and implementing the allocation of various types of energy sources.

Key words: wind power, new energy power, optimal dispatch of power system
