In this paper, the modified Euler-type moving average prediction (EMAP) model is proposed to operate a new energy type dispersed power supply system in autonomous mode. This dispersed power supply system consists of a large-scale photovoltaic system (PV) and a fuel cell, as well as an electric double-layer capacitor (EDLC). This system can meet the multi-quality electric power requirements of customers, and ensures voltage stability and uninterruptible power supply function as well. Each subsystem of this distributed power supply contributes to the above-mentioned system performance with its own excellent characteristics. Based on the collaborative operation methods by EMAP model, the required capacity of EDLC to compensate the fluctuation of both PV output and load demand is examined by the simulation using software MATLAB/Simulink, and, response characteristics of this system is confirmed with simulation by software PSIM.

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, the EMAP model is used to operate a new type of dispersed power supply system consisting of a large-scale photovoltaic system (PV), a fuel cell (FC), and a small-scale superconducting magnetic energy storage system (SMES). This distributed power supply system can meet the multiple-quality electric power requirements of customers, and ensures voltage stability and UPS (Uninterruptible Power Supply) functions as well. Each subsystem of this distributed power supply contributes to the above-mentioned system performance with its own excellent characteristics. Moreover, the response characteristics of this system are confirmed by simulation with PSIM software, and, using collaborative operation under the EMAP model, the required capacity of SMES to compensate the fluctuation of both PV output and load demand is examined by simulation, using MATLAB/Simulink. © 2004 Wiley Periodicals, Inc.

Application of the unified power flow controller (UPFC) to dispersed power supply system combined with fuel cell (FC) and electric double layer capacitor (EDLC) is studied in this paper. This system is operated in autonomous mode, taking account of time delay characteristics of FC. The modified Euler type moving average prediction (EMAP) model is introduced to reduce the capacity of EDLC. This system can meet the multi- quality electric power requirements of customers, and ensures voltage stability and uninterruptible power supply (UPS) function as well. Moreover, the response characteristics of this system are confirmed with the simulation and the required capacity of EDLC to compensate load demand is clarified by the simulation based on collaborative operation methods by a prediction model.

In this paper, a new type dispersed power supply system consisting of the photovoltaic (PV), the fuel cell (FC) as well as a superconducting magnetic energy storage system (SMES) is proposed. The basic philosophy of this concept is described, and the feasibility of this system is confirmed by computer simulation. In order to deal with the PV output fluctuation and the response time delay of FC, the modified Euler type Moving Average Prediction (EMAP) model is proposed, and the capacity of SMES for this system is examined with the simulation.
