Parameters Affecting Electricity Generation by a Photovoltaic Direct Current Micro-grid Connected to Electricity Network

Paying attention to the increasing concerns of global warming, environmental crisis and energy, International research and Development has extended to sustainable energy systems.In this research,Applied method for optimizing the installation space of photovoltaic system Due to the limited space in the buildings of the country's cities, As the effect of the shadow on the efficiency of the panel, The intensity and angle of radiation, In order to produce the maximum calculated energy, That using Meteorological data including sunny hours, cloudy and humid, cities in central Iran classification and Regression model of radiation intensity and sunny hours of each class were identified in SPSS simulation software.Five cities of Tehran, Ahvaz, Yazd,Gorgan and Ardabil were selected and their average radiation intensity was obtained.in order to Generating more photovoltaic energy and increasing the capacity of the distribution network,to minimize the space where the photovoltaic system is installed,Panel angle relative to horizontal surface, Reduce the shadow of each panel compared to the other panel,From the Bee Colony Metabolization Algorithm used in Matlab software and compared to its normal state,also simulation results In the optimal state, It is analyzed and presented with the installed system of electricity subscribers in Tehran. The results show with monthly recorded data of the designated photovoltaic system in Tehran, optimal panel installation space, service and maintenance, reducing shade increases energy production and capacity release and the stability of the distribution network becomes electricity.
