Profit maximization of hybrid system under availability based tariff in deregulated environment

This paper proposes an idea for the profit maximization of hybrid system. Wind plant and pumped storage hydro plant acts as a hybrid system. Profit calculation is mainly based on frequency. Contract is signed between hybrid system and grid. Deviations from contract make unscheduled interchange flow between hybrid system and grid. Load scheduling is implemented in the utility connected load to maximize their profit and to minimize unscheduled interchange flow. The effect of load scheduling on the profit of hybrid system for different wind power is analyzed and compared with the case without load scheduling.
