Abstract

Due to sustainable growth of power demand, high cost of grid upgrade, implementation of electricity market and focus on environmental protection, transmission and distribution networks runs closing to their operating limits, under this back ground, distributed generation is widely applied in modern power system. The interconnection of distributed resources may cause serious hidden troubles to system operation, which is one of the key problems of the mass application of distributed generation, so it is necessary to analyze the characteristic of distributed resources and their impact. This paper attempts to review the impact of distributed resources on electric network, especially distribution network concerning relay protection, voltage regulation, unintended islanding, economic benefit, over voltage, power quality, reliability and cost allocation. Several computational results are summarized. Finally, some other research topics are listed out.
