Power Quality Improvement using PV Integrated Unified Power Quality Conditioner in Distribution System
Power Quality is unease in modern power system for all. Incorporating renewable energy systems, power electronic equipments have brought numerous problems in power system. Here this paper handles with the power quality difficulties that occurs on the distribution network due to various reasons. Here, the proposed one have integrated photovoltaic (PV) Unified Power Quality Conditioner (UPQC) with synchronous reference frame (SRF), instantaneous reactive power, and PI control theory is presented. But those devices are vulnerable to the variations in input voltage generated by involvement between the other parts of system. In the modern age, as there is an increase in costlier sensitive electronic equipment, quality of power received is required by all for a well founded and safe operation in a power system. Power quality problems and low power factor at the PCC in a single load as well as in bus system are here efficiently compensated by the system, which is connected with shunt and series compensaters and a dc link capacitor. The efficacy of the system is studied using MATLAB/Simulink in a 16 bus distribution system under various conditions that causes sag in the system.
