Abstract


With the growing global energy crisis and environmental pollution problems , the development and utilization of renewable energy and green energy in order to achieve sustainable development of mankind must take measures . Solar energy is the cleanest in the world , the most realistic , large-scale development and utilization of one of the most promising renewable energy . Solar photovoltaic power generation is the major trends in the use of solar photovoltaic . However, with the large capacity of PV systems and network , will have a greater impact on the power system to the operation of the system at the same time bring a technical problem , this paper studies photovoltaic system on the distribution power flow , voltage distribution as well as relay the impact . The first grid-connected photovoltaic power generation system and network model established in MATLAB / simulink PV array maximum power point tracking module , inverter module , including grid-connected photovoltaic power generation system model and simulation results demonstrate photovoltaic array model , maximum power point tracking the effectiveness of the control algorithm , as well as the entire system model ; then analyzed the distribution power flow and voltage distribution grid PV systems , power system analysis software PSASP simulation study of a photovoltaic system in different capacity and access location and different operating conditions on system load flow , voltage distribution law , and reactive power regulation , voltage regulation , technical measures and control strategies ; were investigated last study PV system short circuit fault conditions the extent of the current impact analysis of the impact of the different access location , different capacity of PV systems and different fault point location of the distribution network short-circuit current and line protection , and affect the determination of the different strategies .
