Sustainable Utility Interfaced Solar(PV) Power Fuzzy Controlled System Model for Rural India

Electricity is the basic need for economic growth of Indian villages . Although rural houses are grid assisted but the increasing demand of power due to rapid growth of population, the load is managed with existing power resources through load shading. The grid extension has also become standstill due to diminishing trend of raw material as required for power generation. As a result, need has been felt to supplement weak grid power with other green power resources and provide sustainable power supply (24x7) to these rural houses. In order to overcome the increasing demand of electricity, a novel design of utility interfaced solar ( PV) system model has been proposed for a typical load energy requirement of literacy rural house. The PV system integrated with grid has been designed using fuzzy based intelligent controller to share load power among both resources up to 1 kW,. The controller eliminate or minimizes connectivity of load with grid/DG in an optimal way and at the same time provide sustainable power to these literacy houses. The SPWM Inverter technology is used with bidirectional feature to charge the battery of PV system from grid supply as well as to produce SPWM AC power i.e 220V 50 Hz to load at user end with less harmonics. The use of dual battery bank in PV system for storage and delivery of stored energy separately are unique features of system to maintain sustainability. The impact of sustainability feature of PV-Grid power system has been anticipated to create employability with many other benefit for potential youth and expected to enhance literacy rate among neo-literate rural masses in Indian villages.
