Dispatch , Control Strategies and Emissions for Isolated Wind - Diesel Hybrid Power System Bindu

Depleting oil reserves and the growing concerns of global warming, have made it compulsory to seek alternative in form of environment friendly technologies like renewable energy sources. The advantage of hybrid power systems is the combination of the continuously available diesel power and locally available, pollution-free wind energy. With the Wind-Diesel hybrid power system, the annual diesel fuel consumption can be reduced and, at the same time, the level of pollution can be minimized. A proper control and dispatch strategy has to be developed to take full advantage of the wind energy during the periods of time it is available and to minimize diesel fuel consumption. The paper presents two dispatch strategies (i) load following and (ii) Cycle charging along with different system controls. For the proposed system, load following dispatch strategy along with its system control performs better than the cycle charging strategy.
