Multi-unit Japanese auction for device agnostic energy management

Abstract

The energy system is undergoing structural changes due to the integration of volatile electricity generation technology and sector coupling. This article proposes an adapted continuous Japanese auction for device agnostic energy management for a sector coupled energy system. The auction mechanism ensures that no device specific information has to be exchanged. The algorithm is implemented for a single household containing a PV-system, a battery storage, an electric vehicle, a domestic hot water system, and a household load. For every component, a demand/supply function is proposed, which respects the respective physical characteristics. The algorithm is simulated for one year and compared to a reference, which represents an individual control of the devices without considering coordination. Further, two different auctioneers are proposed, one which focuses on energy efficient use of local resources and another one aims to reduce peak load. The results show that the proposed algorithm decreases the peak powers of the investigated system and improves local power usage, i.e. own consumption and self-sufficiency. Thus, this algorithm can reduce grid reinforcement demand due to lower peak powers by better usage of local resources, while satisfying sector coupling needs.
