Abstract: Based on a rural microgrid composed of wind power Turbine (WT) and photovoltaic (PV) generators with energy storage (ES), this paper proposed the multiple-time scale complementary power supply technology. By using the quick power support and charge/discharge characteristics of the ES system, as well as the distributed coordination characteristics of WT and PV power generators, the power supply reliability and security of the rural microgrid could be improved. A typical rural microgrid composed of WT, PV and ES was built based on PSCAD/EMTDC electromagnetic transient simulation platform and the quick power support of ES and multiple-time scale coordination control were analyzed in the simulation model. Simulation results show that the proposed WT/PV/ES complementary power supply technology can solve the low power supply reliability and poor power quality of rural microgrid etc power supply problems.
        Key words: rural microgrid; energy storage; wind power turbine; photovoltaic; multiple-time scale
