摘要：
The volatility and uncertainty of high-penetration renewable energy seriously affect the stability of power systems. In order to meet this challenge and improve the power system's ability to cope with the uncertain disturbances, this paper proposes an optimal dispatch method for high-penetration renewable energy integrated power systems based on flexible resources. First, the flexibility of high-penetration renewable energy integrated power system is analyzed. Secondly, from the two aspects of power supply flexibility margin and flexible adaptability of renewable energy, the evaluation index of power system is proposed. Finally, a multi-objective optimal dispatch model is built based on flexible resources. The simulation results show that the proposed optimal dispatch method can effectively increase the flexibility of the high-penetration renewable energy integrated power system, lower the system backup redundancy, and reduce the pollutant emissions. © 2020, Power System Technology Press.
