Externe Ladeinfrastruktur kann rechtskonform aus dem Stromnetz einer öffentlichen Liegenschaft versorgt werden. Bisher war die Vorgabe, die Versorgung über einen eigenen (neuen) Netzanschlusspunkt zu realisieren. Die hier vorgestellte Lösung ist ökologisch, wirtschaftlich und technisch deutlich günstiger und dient als Muster für die weitere Erschließung landeseigenen Parkraums in ganz Baden-Württemberg. Ein virtuelles Kraftwerk ermöglicht den gemeinschaftsdienlichen Betrieb.
Business opportunities for energy providers to utilize flexible industrial demand are platform-based, connecting small and medium-sized enterprises (SMEs) to a virtual power plant (VPP) in complex ecosystems. Unlike in other VPPs, the focus is on participation, data, and control sovereignty for the SMEs. An exemplary application for an existing cement mill demonstrates positive margins. Viable VPP business models for small and medium-sized utilities include the “orchestrator,” i.e., adding value by linking services of specialized providers, the “integrator,” i.e., incorporating internal and external processes and resources, as well as the “white label user,” i.e., using a turn-key VPP from an exclusive cooperation partner.
The increasing share of renewable energy with volatile production results in higher variability of prices for electrical energy. Optimized operating schedules, e.g., for industrial units, can yield a considerable reduction of energy costs by shifting processes with high power consumption to times with low energy prices. We present a distributed control architecture for virtual power plants (VPPs) where VPP participants benefit from flexible adaptation of schedules to price forecasts while maintaining control of their operating schedule. An aggregator trades at the energy market on behalf of the participants and benefits from more detailed and reliable load profiles within the VPP.
