Study on unit commitment problem considering wind power and pumped hydro energy storage
نویسندگان
چکیده
The stochastic and intermittent characteristic of wind power present great challenge to the operation of power system. A novel unit commitment problem (UCP) model is proposed in this paper. As the status of thermal units need to be described by binary number, Binary Particle Swarm Optimization (BPSO) algorithm is proposed to find the optimum schedule scheme. Case studies on the 10 units system illustrate the efficiency of the proposed approach. Crown Copyright 2014 Published by Elsevier Ltd. All rights reserved.
