AVOIDING GRID CONGESTIONS WITH TRAFFIC LIGHT APPROACH AND THE FLEXIBILITY OPERATOR

While distribution grid operators have to ensure the power supply with well-defined quality constraints, future network nodes such as smart buildings or flexible generation units should be able to offer their flexibility (aggregated in distributed virtual power plants) to energy markets. In certain situations, market-driven operation can conflict with network restrictions on distribution level. Recently, the traffic light model has been adopted in many European smart grid discussions, which distinguishes between free market operation (green) and network restrictions (red). This work focuses on a concrete implementation of the yellow state, which uses local market incentives to avoid network restrictions in advance.
