本文提出了改进的进化编程（IEP）及其混合版本与非线性内部点（IP）技术相结合，以解决最佳的反应式功率调度（ORPD）问题。在IEP方法中，在调节控制变量的突变方向时遵循调节反应能力的常见实践，以增加将状态变量保持在界限内的可能性。 IEP还与IP方法杂交以获得快速初始解决方案，然后在改进的EP方法的初始种群中用作高度进化的个体。与现有的计算效率和最佳性方面的ORPD算法相比，与现有的ORPD算法相比，中国西部的IEEE 118总线系统和现实的电力系统的数值测试非常令人鼓舞。
This paper proposes an improved evolutionary programming (IEP) and its hybrid version combined with the nonlinear interior point (IP) technique to solve the optimal reactive power dispatch (ORPD) problems. In an IEP method, the common practices in regulating reactive power are followed in adjusting the mutation direction of control variables in order to increase the possibility of keeping state variables within bounds. The IEP is also hybridized with the IP method to obtain a fast initial solution, which is then used as a highly evolved individual in the initial population of the improved EP method. Numerical tests of the proposed algorithm on the IEEE 118-bus system and a realistic power system in Western China are very encouraging compared with the existing ORPD algorithms in term of computational efficiency and optimality.
