Project ‘power-to-heat in smart grids’– a multi-objective approach for a maximised value of flexibilities in grids

Abstract

The integration of power-to-heat (PtH) assets as grid oriented flexibilities can help balancing and stabilizing the increasingly strained distribution grid level. As a result of using demand side response, conventional grid reinforcements could be avoided/deferred in certain cases. Furthermore, decentralized renewables could be integrated more effectively. A multi-objective approach aims to improve the economics of the PtH asset using the flexibility in an optimized way. Whereas the grid oriented usage is chosen in certain times of grid restrictions due to fluctuating wind feed-in, system-/market oriented flexibility usage can be applied during the remaining time periods. Besides the technical solution of using different optimized flexibility dimensions, also the regulatory discussion for distribution grid operators is part of this paper indicating a need for actions to enable a suitable usage of demand side response potentials.
