For distribution systems where wind sources are poor, low-wind-speed wind turbines (LWTG) plays an important role in improving the security, economy and reliability of the system. However, the stochastic volatility of LWTG output and loads poses a challenge to the technology of distribution network reconfiguration. Considering the uncertainty of LWTG output, photovoltaic output and changes of load in multiple continuous periods, a dynamic robust reconfiguration model is established. The optimization target is to minimize the three-phase current unbalance and network loss. The model solving process combines the Latin hypercube sampling-based Monte Carlo method, the Semi-invariant method and the compound differential evolution algorithm. The influence of LWTG on the reconfiguration results is explored based on the modified IEEE34-node simulation system, and the performance of the proposed dynamic robust reconfiguration method is then verified.

For substation locating and sizing in the distribution network, the cost of land and geographic information should be considered. A new algorithm based on cultural differential evolution algorithm (CDEA) considering geographic information factor is presented. Based on the improved technique for order preference by similarity to ideal solution (ITOPSIS), geographic information factor model is set up. CDEA is proposed by designing three kinds of knowledge in belief space to guide evolution. The new algorithm overcomes the premature phenomenon of differential evolution algorithm and improves significantly ability of global optimization. Finally the case proves that the proposed model and method is correct, having certain practical value.
