Real-Time Implementation of Electric Spring With Solar PV System in Smart Grid

The paper proposes real time integration of Solar Photovoltaic (PV) System into the Grid. The integrated Photovoltaic System comprises of PV Panel, DC-DC Converter, Inverter and a filter inductor for synchronizing with Grid. Integration of Renewable Energy System (RES) i.e. PV backfires the problems associated with the voltage instability in the grid. In this paper unpredictability and intermittent nature of RES can be surpassed by using the concept of Electric Spring (ES). Amongst the existing ES topologies, the ES-1 configuration has been successfully implemented for the dynamic regulation of grid voltage incorporating conventional voltage regulation control of ES. In addition with grid voltage stability the Maximum Power Point Tracking (MPPT) using Perturb and Observe (P & O) method is also taken into consideration. The simulation results in terms of P-V Characteristics, load Characteristics and ES performance are effectively demonstrated using MATLAB environment.
