Optical Storage Complementary Control Of The Micro-grid System

With the increasing of human demand for energy, coal, petroleum,natural gas and other non-renewable resources dwindling, people graduallyrealized the importance of the development of renewable resources. Solarcharacteristics of a rapidly developing renewable energy rely on clean,environmentally friendly and widely distributed. According to developmentstatus and future prospects of the microgrid at home and abroad, describedthe structure of the micro-grid system. Based on the equivalent circuit of thephotovoltaic cells to build a model of the photovoltaic cells, and verify thecorrectness of the model. Analysis of a photovoltaic cell MPPT controlalgorithm, build BOOST boost circuit and the simulation model of the MPPT control of photovoltaic cells based on the perturbation andobservation method MPPT control circuit.Commonly used in energy storagecharacteristics of the micro-grid, and a detailed analysis of the workingprinciple and control strategy of the battery, battery control strategy in theoptical storage complementary micro-grid system.Designed according to thePQ of the micro-power control and V/f control, optical storagecomplementary micro-grid system, to build a simulation model of theoptical storage of complementary micro-grid system in the Matlab/Simlinkenvironment. Optical storage complementary microgrid in island mode, andthe network switch to an island, island three modes of transfer and networkcan normally run through the simulation test.And optical storagecomplementary micro-grid system electrical power variation andcharacteristics of the micro-grid voltage and frequency. The simulationresults show that optical storage complementary micro-grid system caneffectively improve the utilization of solar energy, and prove that the batteryjoined in the mediation of micro-grid voltage and frequency to stabilize thesystem disturbances to ensure stable operation of the piconet play an important role.
