Studies on power quality enhancement using computational intelligent techniques on renewable energy systems integrated grid

Abstract

The benefits of employing solar photovoltaic electricity to electrify rural areas are quickly expanding. Farmers rely on solar photovoltaic energy because it operates continuously, is easy to build, requires little maintenance, and costs less to fuel. Governments and philanthropic groups are installing or assisting in the construction of photovoltaic systems in remote rural areas to deliver uninterrupted electricity. These programs are extremely common in cities since they allow customers to reduce their monthly energy expenses while assisting utilities during peak demands. Integration of renewable energy sources such as solar PV and wind turbines into power systems require power electronics for its performance improvement. Massive amplitude frequency variations in power distribution networks have a substantial impact on renewable power when unanticipated power imbalances happen. The main reasons for all these frequency changes are the irregular nature of sustainable power and a lack of power electronic controllers. A power semiconductor link between the inputs and outputs is suggested to address the voltage imbalance with the aim of providing voltage output regulation while boosting grid stability. Along with Grid voltage regulation and power factor maintenance, real and reactive power should be delivered concurrently to improve overall power quality. The most economical method to account for actual and reactive powers appears to be grid-connected inverters. The most recent analysis is based on a few seemingly effective methods for controlling the electricity flow in the grids. In order to control the grid-tied inverters, the decoupled P-Q model with the Salp Swarm Optimization approach is proposed. newline
