Distributed In Power System Simulation And Experiment

Energy and the ecology are two important issues facing the worldtoday. People have been trying to seek a clean, efficient renewableenergy to replace oil, coal and other conventional energy sources.Solar and wind power generation has a clean, environmentally friendly,and efficient; two are highly complementary in terms of time andgeographical. Improve the stability and reliability of the system powersupply. A lot of research on solar and wind power generation in thedomestic and international references, the application field is the userload power supply, not only for system modeling and simulation, butalso to build a set of small, distributed generation system. Modeling andsimulation and experimental system can be better analysis of thevarious parts of the system, allowing the system to achieve the purposeof the normal power supply. Established in this paper based on solarand wind power generation in small, distributed power generationsystem to resolve the grid in remote areas difficult to reach andhouseholds scattered areas of household electricity problem.Established a distributed household power supply system is to usewind and solar hybrid power generation, battery storage power intoalternating current power supply of household-type load via theinverter inverse. First overall program design and hardware selection,system consists of solar panels, wind generator, controller, battery,inverter and other modules, solar power system six photovoltaic array inparallel, the inverter square wave inverter, battery pack using the formof three set of two batteries in series parallel. Furthermore, this articledistributed households the key components of the supply systemsimulation, simulation of the PV array to draw the curve of solar cellcharacteristics, the study based on the maximum power point tracking;wind power simulation to achieve the maximum wind energy capture; Simulation of inverter to the DC source replacement batteries for DC,the inverter AC voltage supply load to simulate the fluctuation of thebattery pack voltage inverter for AC voltage and current. Alsodistributed household-use power supply system, a pilot study to studythe operation of the entire system, focusing on the battery charge anddischarge control. The results show that the establishment of distributedhousehold power supply system can load commonly used householdpower supply, with good usability.
