摘要：Power quality is one of a major constraint in power system transmission and distribution. This projectgives an idea on effective control of PV/Wind hybrid power generation scheme for standalone applications. Thissystem consists of PV/wind hybrid energy system, boost dc-dc converter, a three phase DC to AC converter, PWMcontroller and non linear load. The boost converter can supply power to the load depending on the source ofavailability. A synthesized AC output voltage is produced by appropriately controlling the switches using PWMtechnique using average power control to control active and reactive power fed to the load. This technique reduces theharmonics and improves peak voltage. From this control method, the quality of output current is improved and alsocontrols the power flow. Simultaneously the consumer thinks about getting more quality in generated power and tominimize the power tariff. To meet both ends we go for hybrid systems. While implementing Hybrid power system, itmay consist of several issues in protection, synchronization, power quality, etc. This paper describes the consequencesof power quality issues and also the methods to reduce power quality issues using MATLAB simulation.
