Coordination Control Strategy for PV/Micro-turbine Hybrid Micro-grid
摘要
Abstract
In light of the fluctuations of power and voltage in a photovoltaic(PV)generation system,a coordination con?trol strategy for PV/micro-turbine hybrid micro-grid is proposed in this paper,which uses a micro-turbine generation system(MTGS)with fast response and flexible control to smooth the fluctuations of PV generation system.In the micro-grid,the PV system bears the base load from the local region,while the MTGS bears the backup loads when the output of the PV generation system is in shortage.When the PV output power and load demand fluctuate,the active power of micro-sources is coordinated to smooth the power fluctuation. When the bus voltage at the point of common coupling (PCC)fluctuates,the reactive power of micro-sources is coordinated to keep the voltage stable.Software PSCAD/EMT?DC is used in the simulation,and results show that the fluctuations of power and voltage can be effectively suppressed by using the proposed coordination control strategy.Moreover,the fluctuation amplitude of bus voltage at PCC and the corresponding recovery time can be significantly reduced when a fault occurs.关键词
