摘要：This p aper presents a variety of dispatch strategies for hybrid renewable systems including wind turbine, PV panel, fuel cell, and diesel generator and battery b ank. These strategies are distinguished based on the priority of the usage of battery bank, fuel cell and diesel generator in case of power deficit and the precedence of charging of battery bank and filling the hydrogen tank. Fo r a given system, resource and load profile, the performance of the system co rresponding to each dispatch strateg y is evaluated against both cost related and reliability related measures. It is found that the performance of the system is highly under the influence of the dispatch strategy incorporated in the system. Therefore, in sizing hybrid renewable energy systems, dispatch strategy should be also considered as a decision variable that needs to be found along with t he optimum size of other comp onents of the system.
