| Abstract: | The influence to voltage and power flow of distribution network on grid-connected distributed generation (DG) is mainly related to DG site and capacity. Based on the concept of power circle and branch weight, this paper puts forward a new method for site selection and capacity determination of DG. This method takes voltage improving and grid-loss reduction as objective function and considers branch power constraint. It also gives consideration to power supply reliability of essential load. Through practical case analysis, it proves that this method is feasible, which can achieve reasonable configuration scheme of DG in distribution network. |
