Improved Control of Isolated Power System by the Use of Feeding Technique

The lack of energy supplied in rural areas is a chronic problem. In many developing countries less than 10% of the rural population has access to electricity. Rural electrification by conventional means such as grid extension or the use of diesel generator is very expensive. Because of this obstacle standing in front of conventional grid extension to reach the non-electrified regions, reliable and affordable solution is the development of an isolated power system (IPS) that include wind power, solar power, batteries, fly wheel etc in addition to conventional sources. For any reliable electrical system, it is necessary to keep the power balance according to load demand. This paper reviews an efficient solution to the problem of control strategy in IPS. Here It will be shown that how the combination of renewable and conventional energy conversion systems in addition to battery supplies are connected in to isolated grid and operated in grid-forming mode
