Impacts of distributed generation on operation of power systems

The various impacts of distributed generation on power system operation were studied in the aspects of power flow,network loss,static voltage stability,power quality,and system protections.The case of photovoltaic generation was used to analyze the general influence of distributed generation on the distribution system,and the results showed that an appropriate size of distributed generation was beneficial to line loss reduction,cost decrease,and postponing investment in generation,transmission,and distribution capacity.
