The Effect Of Power System Connected With Mass Distributed Generation

With fossil erergy gradual depletion and producing unfavourable effectto environment,it is astrategic problem to the global about the permanentexploitation and safety of energy.It is a very importment thing about theexploitation and utilize of the regenerative energy.so distributed energys applymore and more in the power system.Wind power、photovoltaic power and other new energy power have beenincorporated into the power system，Large number of distributed power saccess operation had a certain impact on the operation of the power system.Therefore, further study of the impact on distributed power connected to thepower system.Firstly, analyzing the effects of the substation and power system after thepower system connected with distributed generation,we research the structuraloptimization of the substation connected with distributed generation in themicrogrid under the genetic method and the fuzzy decision.Secondly, analyzing the effects of the relay protection’s operation after thesubstation connected with distributed generation,we extract to use the power storage to improve little output and output instability of the distributedgeneration,but its performance still need improving at the present time.Finally,instructing the effects of the substation and power system afterthe power system connected with distributed generation，VSC-HVDC is one ofmany problem-solving methods by designing pattern.We guarantee safety ofVSC-HVDC power system, VSC-HVDC monitored control system is veryimportant.
