Abstract
The idea of applying distributed generation resources in distribution systems has become increasingly important due to changes in the distribution systems. Optimal sizing, location, type and installation time of DGs for constructing virtual power plant is one of the important subjects in applying distributed generation in the power system. In this paper, a new method is presented for optimal placement and type of distributed generation units and long term system planning aim to constructing virtual power plant. Minimizing the long term total cost of the system is considered as the objective function. The impacts of applying demand response on expansion planning is also investigated. The Binary particle Swarm Optimization (BPSO) method is used for solving this problem. In order to evaluate the efficiency of the proposed method, the method is tested on the IEEE 33 bus distribution system.
