基于现代内点理论的互联电网控制性能评价标准下的AGC控制策略

分析电力系统中现有电力系统自动发电控制(automatic generation control，AGC)策略的运行情况和存在问题。根据电力系统实际运行情况和控制性能评价标准(control performance standard，CPS)考核要求，提出基于现代内点理论的互联电网CPS标准下的AGC控制策略，建立相应的最优化数学模型，确定解算条件，导出含互补约束条件的非线性规划算法。大量的仿真实验和比较算例表明所提的AGC控制策略能有效地减少AGC机组的下令次数，大幅度提高CPS指标，保证电网频率质量和安全运行，降低电网调节成本，实现电网运行的精细化管理。该成果已在广西电网投入开环运行。

AGC Control Strategy Under Control Performance Standard for Interconnected Power Grid Based on Optimization Theory

An interior point algorithm for automatic generation control (AGC) strategy under the control performance standard (CPS) in the interconnected power grids according to the operation of interconnected power grid and evaluation standard of CPS is presented, after the discussion of the practical operating situation and the existent problems of AGC in power system. The new mathematic optimization model for AGC control strategy is proposed, which can be solved by the interior point nonlinear programming algorithm with the complementarity constraints. Extensive numerical simulations on the practical power systems have shown that this control strategy is promising due to reducing the number of order effectively, improving the CPS performance significantly, and the guarantees of the frequency quality and the safety operation in power system. This control strategy has been applied in Guangxi power grid successfully.
