摘要:On the basis of optimal allocation of distributed generation in conventional distribution network, and considering the characteristics of active distribution system and the influence of controllable loads, a two-layer optimal configuration model of distributed generation is established. The upper layer model is used to solve the optimal allocation and sizing of distributed power sources for active distribution systems and the lower layer model is used to solve the optimal strategy of controllable loads in each period. The output uncertainty of uncontrollable distributed generators, such as wind power generation and photovoltaic power generation, is characterized by box uncertain set based on robust optimization theory.With this model, the optimal configuration of distributed generation can be solved and the factors of operation and dispatch can be taken into account. To some extent, the overall planning and operation of active distribution system can be realized.Finally, the genetic algorithm is used to solve the two-layer optimization model.The rationality of the proposed model, the applicability of genetic algorithm, and the strong ability of global optimization are verified by case studies of IEEE 33-bus distribution system.
