Research on Optimization for Siting and Sizing of Distributed Generation Considering Wind and Light Abandonment and Environmental Cost

摘要

Aiming at the problem of siting and sizing of distributed generation (DG) access distribution network, this paper - based on the multi-scenario method-establishes a model which considers the timing fluctuation of load, wind turbine and photovoltaic power generation, selects the micro gas turbine as the stable output source at the same time, and with the investment cost, operation and maintenance cost, wind and light abandonment cost and environmental cost as the objective function. The model selects 12 typical scenes to represent a variety of situations, and uses the improved particle swarm optimization algorithm. Finally, the IEEE69 standard node system is used as an example to simulate and analyze the results. The results prove the feasibility and effectiveness of the model.
