Performance analysis of Id-Iq active filter in grid interfaced WIND/PV hybrid energy system [articol]

Abstract

Present days the energy crisis is major threat in the country. Moreover the per capita energy plays a important role in growth of any nation. Due to industrialization and living standards the energy demands increasing day to day [1] & [2]. The existing fossil fuels which are used to generate energy to meet current energy demand and those are formed due depletion of biomass, living beings under earth from many years. So these sources will over within few years and not belongs to renewable sources. Researches started concentrating towards renewable energy sources (RES) to meet energy demand due to advantages of their abundant nature [3] & [4]. Among renewable energy sources the wind energy, photovoltaic (PV) are major contributors for energy generation from RES. RES outputs are not constant throughout the operation due to change in inputs like wind seep, temperature and irradiation. To maintain grid interfacing standards to connect these RES outputs, power electronic interface is used [5] & [6]. Power electronic devices will induce harmonics into network due to their nonlinear nature. So power quality as become major issue during connection RES to grid. The modeling and simulation of grid connected wind/PV energy system is implemented in this paper. Ip-Iq control is implemented to control active filter and RES is fed through it. Power quality
