At present, China is based on a large unit, large grid, high voltage single supply power system as the main feature, this centralized power generation, long-distance transmission, grid interconnection effectively reduce the system's spare capacity and strengthening of network synchronization, but difficult to fast-track the end of the long-range changes in load, peak load difference increases will lead to electricity shortage, the line is too far away also increased the net loss. Based on this, we consider reasonable access distributed generation distribution network optimization, in order to ...
