| 风能等间歇式能源并网将是未来电网发展趋势, 其输出功率的波动将加剧一二次调频之间的冲突反调问 题. 本文将反馈微分博弈应用于电力系统频率控制中, 建立起一二次调频的协同控制模型, 并考虑调速器死区、控 制动作幅值限制、机组爬坡速率约束等工程实际因素, 用协同进化算法求得该模型的反馈纳什均衡解. 用仿真验证 了该方法在满足各种工程因素下有效解决一二次调频的冲突反调问题, 充分挖掘了系统蕴藏的调频能力. |
| 英文摘要 |
| In the integration of renewable energy such as wind power, the conflict between the primary and secondary frequency control in power system is severe because of the great uncertainties of the output power, which costs more wear and tear of the regulating units. We propose a new frequency control framework based on feedback differential game theory to solve this problem. As an example, a frequency control system model is set up with considering some complex constraints such as the dead zone of governor, the limit of controlling movement amplitude and the constraint of climbing speed of units. The proposed cooperative control strategy of this model is solved by a co-evolutionary algorithm. Simulation results show the new control strategy can relieve the conflict while meeting complicated engineering factors, and fully exploit the frequency control ability of the system. |
