From the outside, the VPP looks like a single power production facility that publishes one schedule of operation and can be optimised from a single remote site. From the inside, the VPP can combine a rich diversity of independent resources into a network via the sophisticated planning, scheduling, and bidding of DER-based services. Peter Asmus examines the role energy storage can play within this architecture.
Commercially viable energy storage has the potential to change the game by solving the energy trilemma. Arshad Saleem, from KIC InnoEnergy, which invests in and supports European sustainable energy, says marrying start-up innovation and big business experience could accelerate the journey to viability.
For over a decade, net metering has been a crucial component of the economic puzzle for renewable energy, allowing both residential and commercial rooftop PV owners to realise favourable returns on their solar equipment investment. John Merritt of Ideal Power Conversion looks at some of the arguments and counter-arguments and says solar-plus-storage could be the natural successor to the policy - starting at commercial and industrial (C&I) level.
