摘要
从发电容量充裕性控制的角度考虑,将需求侧日常限电措施视为预防控制,将事故后停电措施视为事故后控制(包括紧急控制、校正控制)。为了使日常限电容量配置的经济性达到最优,可以用事故后控制代价来反映配置风险,并充分利用预防控制与事故后控制之间的技术与经济互补特性。基于风险管理观点与协调优化理论,以预防控制代价与事故后控制代价之和最小为目标函数,建立了优化日常限电容量配置的决策模型,并采用数值灵敏度技术的寻优算法来求取最优的配置量。仿真结果表明,基于事故风险优化日常限电容量配置能够有效地提高发电容量充裕性控制在需求侧实施的经济性。
In the control of generation capacity adequacy, the normal electricity restriction at demand side is regarded as preventive control and the post-incident interruption as emergency/corrective control. In order to economically optimize the configuration of normal electricity restriction capacity, the cost of post-incident control is taken to reflect the configuration risk and the inter-complementary properties in technique and economy between preventive and corrective controls is fully utilized. Based on risk management and coordination optimization, the decision-making model is established to optimize the configuration of normal electricity restriction capacity, which uses the sensitivity technology based optimization algorithm to search the optimal capacity configuration and takes the minimal sum of preventive control and corrective control costs as its objective function. Simulation results validate that, the optimization of capacity configuration for normal electricity restriction based on post-incident interruption risk can greatly improve the economy of generation capacity adequacy control at demand side.
