OPTIMUM OPERATION OF LARGE-SCALE WIND-DIESEL GENERATION SYSTEMS

This paper presents a new approach to minimize the operation cost of w ind-diesel system. Under the constraints of diesel units' startup/shut down time, ramp rate and power balance etc., the 'Unit Commitment' co ncept is introduced to construct the model for optimal operation plann ing of all the diesel units. Dynamic programming (DP)method is applied to solve the problem. A test system is used to demonstrate the featur es of our proposed method and some interesting results are reached.
