摘要
剖析了智能电网的发电—用电充裕性评估及控制任务。从需求、扰动、控制对象和控制时滞等方面梳理问题的复杂性;讨论充裕控制的决策过程,包括对信息的要求、待调控出力的预报、充裕性事件的设定、充裕度量化指标的定义、系统功率平衡与备用功率的动态行为、充裕度的在线评估、备用资源的调度与控制。提出基于风险观点的动态优化及解耦协调的求解思路,将整个问题解耦为不同子问题后分别优化,再通过协调获得全局准优化的效果。
This paper analyzes the assessment and control tasks of smart grid operation adequacy.The complexity of the problem is dissected in terms of demand,disturbance,controlled objects and time-lag.The decision-making process of adequacy control is also discussed including information acquisition,estimation of the needed dispatch power,parametrization of adequacy events,definitions of adequacy index,dynamics of power balancing and reserving,on-line adequacy assessment, dispatch and control of reserve resources. A risk-based conceptual model for dynamic optimization is presented, and a decoupling and coordination solution method is also proposed to give a global quasi-optimum result.
