DISTRIBUTED GENERATION OF POWER USING RENEWABLE ENERGY RESOURCES-A COMPARATIVE REVIEW OF GRID-CONNECTED & STANDALONE SYSTEM

Off-grid power generation system has several complimentary functional applications and succinctly, it has been regarded to be an important technology to realize as its reliability, sustainability and techno-economic solution of energy. Among various decentralized generation techniques, hybrid renewable energy source (HRES) is one of the promising techniques in terms of sustainable, simplicity of operation and commissioning. The most common hybrid systems, preferably used are PV/Wind/Battery and PV/Diesel/Battery accordingly feasibility of these sources. In the recent years, HRES have been developed as new age technologies for the faster meeting the load demand in the remote area with superior combinations. Experimental investigations done by the researchers using the hybrid optimization model for electric renewable (HOMER) involved (a) study area characterization (b) resource assessment (c) load demand for the domestic, agricultural, community and commercial (d) expected different combination of RES and (e) optimization analyses in order to achieve objective function by attempting a number of combinations of RES. Based on the optimization technique the result has been evaluated with the help of different parameters as decision variables, sensitivity variable. The optimization aim was carried out in different cases regarding minimization of per unit energy cost (PUEC) and the emission of greenhouse gases (GHGs).
