提出了一种有效的分析方法，用于优化配置多种分布式发电技术，以最大限度地减少配电系统的功率损耗。考虑了不同的DG类型，并对其功率因数进行了优化计算。提出的EA方法也适用于分配不同发电能力的不同DG类型的最优组合问题。此外，将EA方法与最优潮流（OPF）算法相结合，提出了一种新的EA-OPF方法，有效地解决了系统的整体约束问题。采用33-母线和69-母线配电测试系统对所提方法进行了测试。通过穷举OPF算法对两个配电网的精确最优解的仿真结果验证了计算结果。结果表明，所提方法在计算速度和精度上均优于现有方法。
An efficient analytical (EA) method is proposed for optimally installing multiple distributed generation (DG) technologies to minimize power loss in distribution systems. Different DG types are considered, and their power factors are optimally calculated. The proposed EA method is also applied to the problem of allocating an optimal mix of different DG types with various generation capabilities. Furthermore, the EA method is integrated with the optimal power flow (OPF) algorithm to develop a new method, EA-OPF which effectively addresses overall system constraints. The proposed methods are tested using 33-bus and 69-bus distribution test systems. The calculated results are validated using the simulation results of the exact optimal solution obtained by an exhaustive OPF algorithm for both distribution test systems. The results show that the performances of the proposed methods are superior to existing methods in terms of computational speed and accuracy.
