A new generation of load controllers enable stand-alone power systems (SAPS) to use one or many, standard (grid connected) wind turbines. The controllers use fuzzy logic software algorithms. The strategy is to use the control loads to balance the flow of active power in the system and hence control system frequency. The dynamic supply of reactive power by a synchronous compensator maintains the system voltage within the limits specified in EN50160. The resistive controller loads produce a certain amount of heat that is exchanged down to the end user (hot water). It was decided to investigate the implementation of a hydrogen subsystem into the SAPS that can work in parallel with the Distributed Intelligent Load Controller (DILC). The energy storage on long-term basis and an active load hydrogen subsystem can then function as energy ad controller on short-term basis. (c) 2005 International Association for Hydrogen Energy.
