The basic framework for tuning Genetic Algorithm (GA) is to bring the system to stable condition with proportional Integral controller for DC-DC converter (Buck -Boost Converter) which is applied to PV source. Due to its non-linear characteristics, the performance of the controller needs to be improved in order to improve its efficiency. The gating pulses of the converter uses Pulse Width Modulation (PWM) technique in order to reduce its THD level. The main purpose of PI controller is to bring down the large values of instabilities in the system response and to reduce steady state error which in turns improves the gain and accuracy. Genetic Algorithm (GA) is a search algorithm to solve optimization problems. The controller parameters are optimized to produce reasonable transient response without affecting the stable operation. Output voltage magnitude of DC–DC converter is either greater than or lesser than the input voltage magnitude. Variable DC voltage from PV panel is applied to DC – DC converter to get constant DC output voltage. The modelling of the Proposed system is modelled using MATLAB/SIMULINK and its results are verified.

In this article, a seven-level inverter powered by solar has been proposed to achieve a sinusoidal output voltage with high efficiency and enhanced power quality. This system consists of active inverter and flipped condenser clamping. It gives output voltage level of 2/3. By connecting the switched condenser branch in the front or back end series to the inverter output a seven-level output voltage wave shape can be obtained with ample non-work switching states to match the voltage of switching condensers. The consequence of the proposed method is validated using MATLAB SIMULINK for simulation. Comparing with conventional seven-level inverter topology, the proposed design used a minimal number of switches using a basic modulation process.

Grid connected photovoltaic system is used to watch the soundness and execution of the framework. The easiest strategy is to gather and transmit the information across information links. Customary wired checking framework gives dependable arrangement in information transmission yet experiences a few restrictions. The utilization of information links likewise builds establishment and upkeep cost. Information links are influenced by the sun pillar and downpour. Checking station should be found sensibly near the observing plant. To conquer these issue Zigbee based remote checking framework is created for web based observing of a lattice associated photovoltaic framework. A PC-based application coordinated with online capacity is planned and executed so as to permit controller of the framework just as simple access of the information over the web. Boundaries like temperature, illumination, PV power yield and framework inverter power yields are checked. To approve the presentation, the framework has been executed on 100Wp network associated photovoltaic framework.
