摘要: |
提出一种含多类分布式电源的多目标配电网重构模型。在重构时采用Pareto准则的多目标二进制粒子群优化(Multi-Objective Binary Particle Swarm Optimization, MOBPSO)算法,对算法进行了3点改进:基于环的编码方式用以降低不可行解的产生概率;动态变化的惯性因子和异步变化的学习因子用以提高算法的调节适应能力;在最优粒子的更新方式上提出小生境共享机制和比例选择算子相结合的策略。最后还给出了一种根据决策者偏好信息,从优化解集中选择相应重构方案的评价机制。算例结果表明:改进的MOBPSO算法在寻优效率和稳定性上均有提升;所提模型、改进算法以及评价机制互相配合,能够为决策者提供一种有效的配电网重构方案。 |

Abstract: |
A distribution network with multi-type distributed generations reconfiguration model considering multiple objectives is proposed. Pareto optimal criterion and multi-objective binary particle swarm optimization (MOBPSO) algorithm are used in the reconfiguration process. The algorithm is improved in three aspects: the ring-based coding method to reduce the probability of infeasible solutions; the dynamic change of inertia factor and the asynchronous change of learning factor to improve the algorithm's adaptive ability; combination of niche sharing mechanism and proportional operator selection are proposed to update the particles. According to the decision maker’s bias, this paper finally gives an evaluation mechanism, which can select the appropriate reconstruction scheme from the optimal solution. Numerical results show that the improved MOBPSO algorithm can improve the efficiency and stability of the optimization. This paper’s mode as well as the improved algorithm cooperating with the evaluation mechanism can provide an effective reconfiguration scheme for decision maker. |
