Power-Dependent Price Profiles - Defining Grid- and Market-Oriented Incentives for Building Energy Management Systems

In order to consider the grid- and market-oriented situation of the energy system and provide corresponding price signals for building energy management systems (BEMS), we propose time- and power-dependent price profiles. Those incentive signals are meant to allow the optimization of BEMS towards dynamic prices while providing a clear incentive to limit power during grid congestion. We evaluate those signals with a generic battery optimizer that is capable of optimizing towards them. Simulations show that those time- and power-dependent grid signals can reduce peak loads in distribution grids while at the same time allowing more market orientation than volumetric dynamic grid fees.
