Abstract
In this paper, the modified Euler type Moving Average Prediction (EMAP) model is proposed in order to operate a dispersed power supply system using new energy in autonomous mode. Furthermore, EMAP model is applied to operate a new type dispersed power supply system consisting of a large scale photovoltaic system (PV), a fuel cell (FC) as well as a small scale superconducting magnetic energy storage system (SMES). This distributed power supply system can meet the multi-quality electric power requirements of customers, and ensures voltage stability and UPS (Uninterruptible Power Supply) function as well. Each sub-system of this distributed power supply contributes to the above-mentioned system performance with its own excellent characteristics. Moreover, response characteristics of this system are confirmed with simulation by software PSIM, and, under collaborative operation methods by EMAP model, the required capacity of SMES to compensate the fluctuation of both PV output and load demand is examined by the simulation using software MATLAB/Simulink.
