Impact of distributed generation on electricity prices at buses in distribution networks

摘要

The article represents the research result on simulating mathematic calculation of electricity price at buses without distributed generation (DG) and with DG. The article aims at comparing the impact of DG on the electricity price at buses. The simulation results showed that when DG is integrated into the distribution network, the price signals are more efficient and the power losses reduce in the network. Electricity price in a competitive electricity market depends not only on locals but also time; and it can regulate the load and adjust the behavior of the market participants in order to ensure system security. The simulation results help the owner of DG sources have further information to successfully give out market bidding strategy.
