Novel Control Strategy for Enhancing Microgrid Operation Connected to Photovoltaic Generation and Energy Storage Systems

Recently, the penetration of energy storage systems and photovoltaics has been significantly expanded worldwide. In this regard, paper presents enhanced operation control DC microgrid systems, which are based on photovoltaic modules, battery load. DC–DC DC–AC converters coordinated controlled to achieve voltage stability in microgrid. To such an ambitious target, system is widely operated two different modes: stand-alone grid-connected modes. The novel strategy enables maximum power generation from across techniques for operating Six cases simulated analyzed using MATLAB/Simulink platform while varying irradiance levels consequently generation. proposed achieves at load demands. It illustrated that grid-tied mode regulated by source converter offers more than islanded mode. general, introduces a stable but with few spikes. merit integrated batteries attain further flexibility reliability through balancing demand simulation results also show can operate properly normal or abnormal cases, thanks strategy, regulate bus photovoltaics.
