Title The micro_grid energy mangement and system design_the part of photovoltaic power generation
Abstract
With the energy shortage, electricity demand growth, resource consumption serious problem has become increasingly prominent，The emergence of micro-grid technology has become a hot topic，micro-grid is a cutting-edge research areas，Clean, safe photovoltaic technology used in micro-network is of great significance。Due to time constraints，This paper focuses on the micro-grid photovoltaic power generation unit analysis, in order to achieve the use of clean energy, relieve pressure on the power grid, improve the load power supply reliability .The design of photovoltaic power generation unit and network conditions control strategy is to achieve maximum power tracking under normal lighting conditions.
Paper design grid PV power unit under the control strategy to achieve a normal lighting conditions the maximum power tracking.
This article In the MATLAB / simulink environment ，the photovoltaic power generation unit of the simulation model, right photovoltaic arrays maximum power point tracking, the interface inverter control conducted a simulation analysis was established , simulation results verifying the energy control strategy is feasible and correctness of the strategy.
Keywords : Microgrid, PV, MPPTcontrol
