摘要：
In this paper, an optimal energy management model of a solar photovoltaic-diesel-battery hybrid power supply system is presented. The aim is to meet the load demand completely while satisfying the system constraints. The model proposed minimizes fuel and battery wear costs, and finds the optimal power flow taking into account photovoltaic power availability, battery bank state of charge and load power demand. The results are compared for cases when the objectives are weighted equally and when a larger weight is assigned to battery wear. The results depict the optimal decisions considered in the presence of trade-offs between the two conflicting objectives. (C) 2014 The Authors. Published by Elsevier Ltd.
