Modeling and Simulation using MATLAB to Mitigate Technical Challenges & Also for Scalability of Pilot Project of Clustered Solar Agricultural Feeder

Abstract

The inclusion of renewable energy in India’s electricity mix has been increased dramatically in the past several years. From an environmental, energy security and long-term cost standpoint, this evolving trend is undoubtedly welcome. Solar energy has rapidly emerged as a reliable, affordable and clean solution for meeting India’s fast growing energy demand and supply to all. But connecting PV plant DC power with the AC grid is difficult because of tripping, not properly synchronizing. In this paper the development of PV array model, their integration, power quality assessment and Simulink implementation are described. Modeling concept presented in this paper can easily be extended and used for scalability purpose. System consist of solar arrays, MPPT, IGBT inverter and transformer. First, the field parameters has been measured and analyzed by using Fluke Power Analyzer, then exact field modeling and simulation of cluster model of 1.6 MW grid (agricultural feeder)connected PV based solar power plant using MATLAB Simulink R2019A is made in which Maximum Power Point Tracking technique(MPPT) for obtaining maximum possible power output is used, and in MPPT we have used Perturb and Observe method. The ideal values getting from MATLAB Simulation and the real time values of the PV Plant measured by fluke power analyzer are compared and analyzed, then an efficient systems can be modeled for proper synchronization with the grid.
