【摘要】：提出一种将预防控制和校正控制相协调的电力系统静态安全混合控制方法。预防控制模块中,利用风险指标确定进入预防控制模块的预想故障集,该风险指标考虑了预想故障发生的概率及其严重性,采用连续线性规划技术求解考虑多预想故障的静态安全预防控制策略。校正控制模块中,首先判断系统静态安全裕度是否满足要求,并考虑风电/光伏的随机波动特性,针对不安全故障分别制定校正控制策略。所提方法通过系统风险指标协调预防控制和校正控制中考虑的预想故障集,从而将预防控制和校正控制相互协调,以获得安全性和经济性均满足系统需求的静态安全控制策略。以我国某682节点系统的算例验证了所提方法的有效性。
[Abstract]:A hybrid static security control method for power system is proposed, which combines preventive control and correction control. In the preventive control module, the risk index is used to determine the expected fault set into the preventive control module. The risk index considers the probability and severity of the expected fault. The continuous linear programming technique is used to solve the static security preventive control strategy with multiple preconceived faults. In the calibration control module, the static safety margin of the system is first judged to meet the requirements, and the random fluctuation characteristics of wind power / photovoltaic are taken into account, and the correction control strategy for unsafe faults is formulated separately. The proposed method coordinates the preconceived fault sets of preventive control and correction control by system risk index, so that the preventive control and correction control can be coordinated with each other in order to obtain a static security control strategy that meets both the security and economic requirements of the system. The effectiveness of the proposed method is verified by an example of a 682-bus system in China.
