摘要:
 为实现大容量，特高压电网的低频恢复，提出一种多元联合的紧急低频控制策略，将抽水蓄能、发电机热备用、精准切负荷以及常规切负荷四种手段相互结合来进行联合频率控制。协调几种手段之间的动作轮次和频率点，建立系统频率又快又好恢复及负荷损失最小作为目标函数，并给出相应的约束条件。在策略求解方面，通过模拟退火算法优化求解每种策略启动轮次的最佳频率动作值，算法求解结果给出具体的整定方案。通过PSASP软件对某片区电网进行仿真，实例验证了该策略的有效性和快速性，提供了有效解决措施和方案。
Abstract:
 At present, with the development of ultra-high frequency transmission line, it is easy to take a large number of low-frequency power loss caused by the construction of ultra-high frequency transmission line. In this context, this paper proposes a multi-element joint emergency low-frequency control strategy, which combines pumped storage, generator hot standby, accurate load shedding and conventional load shedding to carry out joint frequency control. The action rounds and frequency points between several means is coordinated to establish the fast and good recovery of system frequency and the minimum load loss as the objective function, and give the corresponding constraints. In the aspect of strategy solution, the simulated annealing algorithm is used to optimize the optimal frequency action value of each strategy start cycle, and the algorithm solution results give a specific setting scheme. Through the simulation of a regional power grid with PSASP software, an example verifies the effectiveness and rapidity of the strategy, and provides effective solutions and schemes for realizing the low-frequency recovery of large capacity and UHV power grid.
