What is a Solar Microgrid? A solar microgrid is a localized energy system that integrates solar panels, energy storage devices (such as batteries), and often other renewable energy sources like wind or hydroelectric power.
The name implies the principle component in a PV-based microgrid is the solar PV system. However, the generated output power of a PV system is dependent on the weather condition, that is, solar irradiance and temperature; and the intermittency in the solar irradiance causes fluctuations in the generated output power of the solar PV system.
The present energy development is the hybrid system projection in which renewable sources and storage systems provide a high percentage of energy needs, leaving the use of conventional system for emergency cases. Hence, microgrids represent a workable solution for the electricity demands in isolated or non-electrified areas.
In order to overcome the problems associated with the intermittency of solar PV and enhance the reliability, energy storage systems like batteries and/or backup systems like diesel generators are commonly included in the microgrids [11, 12].
Microgrid The microgrid is nothing but the integration of number of renewable energy sources, stroge system, and different power electronics converters for control the power flow between grid and load. Here the energy sources are solar PV/Fuel cell/Wind and battery.
Situations of dump energy occur in the stand-alone systems. Integrating the microgrid to the distribution grid is the best way to overcome this situation. LEP of an energy system is defined as the ratio of the energy that is wasted in the system to the total energy demand of the system annually.
