<p>The use of solar photovoltaic (PV) system has grown significantly in Malaysia after Renewable Energy Act has been gazetted in 2011.The objective of this paper is to highlight the technical and economic analysis of solar PV DC system to generate enough energy for residential customer group that consumed 200 kWh per month so that they are less dependent on energy from the utility grid. The results are then compared to the solar PV AC system with similar load setup. The methodology involves gathering solar energy resource, configuring daily load demand, sizing PV array, battery bank and inverter and lastly simulation of the design system by using Homer software. Based on Homer simulation, the solar PV AC system required slightly larger PV array sizes than the solar PV DC system to compensate losses due to the inverter efficiency which is not counted in DC system.Moreover, the solar PV AC system is almost 8.0% more expensive with 6% higher COE than the solar PV DC system due to the present of inverter.Lastly, both systems will benefit from reduction of energy consumed up to 2,434 kWh annually and to the environmental aspect, will avoid 1.7 tons of CO<sub>2</sub> releases into the atmosphere.</p>

“…All this demand growing is also increasing the interest of how the meteorological condition plays significant role in the performance of renewable energy systems, whereas these systems produce optimum output under certain desired weather conditions which are essentially location [3]. Thus we need apply an intelligence network that allows the integration of large amounts of green energy, improving reliability, quality of supply and ensuring safety, due to the great advantages and developments on renewable energy, it is necessary to analyze how energy should be used in a micro-grid [4].…”

The worldwide use of renewable energies sources is steadily growing, due to demand to get new means that allows the support of massive use that it give in the common life, with the final purpose of decrease the use of nature reserve to produce it, in this case is exhibited the necessity to create systems to generated resources in an efficient way, using unlimited power infeed, as example we found the solar energy. This work shows the results obtained by perform a comparative analysis between the static behaviors and the design of a fuzzy logic controller for solar photovoltaic tracking system, defining the photovoltaic position from the maximum solar irradiation presented in 90 degrees; for verification of the result obtained by the controller, we make de simulation of a solar irradiation based in the data of the weather station of the Corporación Autónoma Regional de Cundinamarca (CAR), situated in the campus of the Nueva Granada Military university. 

“…Presently, the dc power generated by the renewable sources has to be converted to ac before it can be transmitted to the loads through a transmission system designed to work on ac. At the load side, the power which is received has to be converted to dc inorder to be used by these devices and these conversions involve power losses [6]. There are millions of such conversions taking place in the entire world each second and thus, a huge amount of power is being wasted.…”

Abstract-Renewable energy sources has become tremendous area of attraction for researchers and industrialist. This attraction leads to look for DC micro grid installation to save energy. DC micro grid systems are of different types. Standalone DC micro grid system is very useful for remote places etc. The standalone DC micro grid system uses a battery backup along with renewable energy source. The battery has to be connected with a DC -DC bi directional converter. This bi directional converter decides and controls the flow of power from source to load and battery and from battery to load when source is not available. The control strategy of this bi directional converter plays a very important role for the reliable operation of DC micro grid. In this paper a new simplified control strategy for bi directional DC -DC converter is proposed. A simple automatic control mechanism based on the sensing and comparison of voltages on both sides of the converter has been proposed. This control strategy is aimed at providing a smart, user-friendly, economical and efficient control. Solar Photovoltaic is taken as renewable energy source. The circuit is simulated using PSIM.
