Application of Demand Response Scheme for Generation Scheduling and Dispatch for Reducing Generation Cost

Demand response (DR), a program motivates consumers to change their load in a period. The response load demand is being a problem in unit commitment (UC). However, UC is related to fulfilling load demand and minimizing the total operation cost of the generating unit without violation of the system and unit constraints. The UC and DR problems are solved using Mixed-Integer Quadratic Programming (MIQP). Load shifting affected by the application of DR is going to affect the percentage of load factor. The higher percentage of load factor has a potential benefit for the utility. The performance of the proposed method is tested using the standard IEEE 10-unit test system. The simulation result shows that the proposed method is capable of increasing 5 load factor with DR. The simulation result also show that the proposed method is capable of reducing at 0.59 of the total generation cost.
