Implementation of a Real Time Supervisory Controller for an Isolated Hybrid (wind/ Solar/diesel) Power System

[email protected] In most of the developing countries like India and South Africa, there exists still many remote places (isolated from the grid); where the electrification is unavailable due to the financial aspect related to establishing the infrastructure to distribute power over a long distance and consequent high transmission losses. Authors emphasize for an Autonomous Hybrid Power Systems (AHPS), which will eradicate the problems faced by the remote places. Integration of Wind/Solar/Diesel also ensures the prompt availability of power to primary health clinics, high way petrol bunks, schools and the basic communication networks located in remote places. In this scheme, DC power is generated by the wind turbine and solar and DC is connected to the load through an inverter. While doing so, the quality of the power as well as the variations in the environmental conditions does not disturb the loads connected. Therefore the reliability is also ensured in power generated with the AHPS. It is easy to construct the plant with 300W capacity on the roof top of the building; with a meager cost of around $1200.
