    FlexControl is a vision, a concept and a product – a vision for the control of future power systems based on renewable energy and distributed control, a generic concept for smart control of many power units and ‘product’ implementations of the concept in different applications. The general development trends for power system towards more stochastic power generation from wind and solar, more distributed generation and control, and the introduction of demand responses from a huge number of small, flexible loads, require new architecture, design and means of controlling of the power system in order to maintain the power balances and the high security of supply and power quality in all parts of the grid. FlexControl is a flexible, modular, scalable and generic control concept designed for smart control of a huge number of distributed, controllable power units (DERs) in the power system. FlexControl is based on aggregated, indirect and rule based communication and control, and open standards. The indirect control is based on responses to the frequency, the voltage and the broadcasting of global or local price signals. The paper presents an overview of the FlexControl concept, with its elements, options and applications.
