Integrated Grid by Using Dual Voltage Source Inverter for Power Quality Improvement

Abstract

In this, we proposed a new concept for enhancing the power quality in unified grid system which is known as dual voltage source inverter. Our proposed approach consist of two converters, which permits the micro grid to trigger power generated by the distributed energy sources (DERs) as well as to compensate the neighborhood unbalanced and nonlinear load. This paper presents a dual current source inverter (DVSI) plan to boost the ability quality and reliability of the micro grid system. These DG models with coordinated control of local generation and storage facilities form a micro grid. Inside a micro grid, power from various renewable energy sources for example fuel cells, solar (PV) systems, and wind energy systems are interfaced to grid and loads using power electronic converters. The control algorithms are developed according to immediate symmetrical component theory (ISCT) to function DVSI in grid discussing and grid injecting modes. The suggested plan has elevated reliability, lower bandwidth dependence on the primary inverter, lower cost because of decrease in filter size, and usage of microgrid power while using the reduced electricity-link current rating for the main inverter. These functions result in the DVSI plan a promising option for micro grid offering sensitive loads. The topology and control formula are validated through extensive simulation results.
