Optimal configuration of distributed generators in an integrated energy system

摘要: The increasing penetration of distributed generators (DGs) makes further interconnection multiple energy carriers possible. In this paper, an integration model comprising IEEE-33 bus distribution network and a correspondingly designed water system is proposed with DG coupling thermal electrical energy. integrated incorporates the constraints network, system, DGs ensures that demands are satisfied simultaneously by flow. An optimal procedure including sizing, positioning, operation gas boilers in given was implemented while minimizing total costs investment operation. constitutes mixed integer nonlinear problem, as it takes power flow calculation characteristics efficiency into consideration. Therefore, particle swarm optimization algorithm employed to simulate model. simulation results conjunction numerical studies reveal impact on configuration advantages economic considerations, voltage level, net loss.
