This document provides performance test methods specialized for the thermal and electrical characteristics which are required by an energy management system to effectively share the heat and power of networked small stationary fuel cell power systems. These test methods are applied for each small stationary fuel cell power system. This document covers small stationary fuel cell power systems which can be complimented with a supplementary heat generator and/or a thermal storage system such as: output: rated electric power output of less than 10 kW for each system; output mode: grid-connected/independent operation or stand-alone operation with alternating current (AC) output not exceeding 240 V or direct current (DC) output; operating pressure: maximum allowable working pressure of less than 0.1 MPa (G) for the fuel and oxidant passages; fuel: Gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen) or liquid fuel (kerosene, methanol); oxidant: air. This document does not apply to small stationary fuel cell power systems with electricity storage other than (small scale) back-up power for safety, monitoring and control. Note: Regarding data linkage for conducting performance tests specified in this document with operating management systems (Energy Management System) of multiple Fuel Cell Power System (mFCPS), an appropriate IEC standard is recommended to select and implement. The related standards are IEC 61850-7-420, IEC 61850-90- 27, IEC 62394 Ed4.0, IEC 62746-10-1, IEC 62746-10-3 Ed.1, etc. The data linkage and implementation for realizing the functions of the system that monitors mFCPS and peripherals differ depending on the vendor of the mFCPS control system, so the methods for data linkage and implementation are not specified in this document.
