A realised control system for a hybrid system consisting of a PV-plant and steam engine with combined heat and power

This paper presents part of a research project done at the chair of electrical power engineering of the FernUniversitat of Hagen/Germany and describes a practical realised control system for a hybrid system, consisting of a PV-plant linked to a steam engine. This is a special complex self-sufficient energy supply system with combined heat and power, which enables the usage of a highest possible portion of renewable energy. The control system is based on a microcontroller and is implemented in a self-made box to get an independent unit. The underlying control concept as well as the hardware realisation ought to give a high degree of flexibility for extension and adaptation to similar hybrid systems. The most important information concerning the concept, hard- and software are presented
