  • Abstract:

        With implementation of demonstrative projects on storage device assisting thermal power units with AGC (Au-tomatic Control Generation) in power grid, extensive attention is drawn by research on storage optimal configu-ration. However, it is difficult to reach a balance between technicality and economy for battery energy storage system (BESS) applied in such case. Aiming at this issue, firstly, this paper builds a double-layer model, of which the first layer is set to minimize both equivalent life loss of BESS and bias electricity for optimal operation, while the second layer, named as economy layer, is built to maximize annual benefit under Kp reimbursement. Secondly, a nested algorithm of Self-adaptive Global Harmony Search and Multiple Objects Particle Swarm Optimization (SGHS-MOPSO) is constructed to solve this model. Finally, based on operation data of a 1000MW-rated unit, capacity configuration of BESS gets optimized and by comparing indicators both in technology and economy, the feasibility of proposed method gets verified.
