考虑联络线支援波动约束的多区域AGC最优联合调频控制策略
Optimal Cooperation Frequency Control Strategy of AGC in Multi-area Under Tie-line Support Volatility Constraint
摘要
Abstract
With large amount of renewable energy resources integrated into strong coupling interconnected power system (IPS), the conventional automatic generation control (AGC) strategy leads to the increase of the AGC regulation cost and the uneven distribution of the AGC regulation amount. This is a serious threat to the frequency stability of the IPS. Cooperation of AGC in different control areas is an effective way to solve this problem. In order to achieve the optimal coordination of multi-area AGC, the relationship between the optimal coordination frequency control model of multi-area AGC and area regulation marginal cost (ARMC) of different AGC was studied. Based on this, considering the fluctuation constraint of tie-line support, an optimal coordination frequency control scheme of AGC based on ARMC was proposed. By linear theory and the improved dynamic model of IPS, the proposed strategy had been proved to be stable and optimal and the range of control parameters was determined. The simulation results of a 3-area system showed that, the control scheme based on ARMC revealed the coordination mechanism of multi-area AGC. Besides, it is more effective for frequency and more economic comparing with other control strategies while keeping the safety of tie-lines.关键词
