Transactive Energy Market Framework for Decentralized Coordination of Peak Load Shaving within a Cluster-of-Commercial-Buildings

Controllable electrical assets in demand centers can be leveraged for peak shaving within demand centres, which may be beneficial due to multiple distribution system factors including power limits in distribution lines and transformers, peak capacity charges, etc. The upcoming Transactive Energybased market at distribution level can be utilized to enable scalable coordination among demand centres, such as commercial buildings and households, for peak shaving as an additional objective. In this paper, an extension is proposed for our earlier generalized hierarchical Transactive Energy-based multi-agent framework for cluster-of-buildings. This framework includes energy management demand agents (EMDAs) at the building level which coordinate the operation of different appliances within the buildings. EMDAs also actively participate on dayahead Walrasian market at the cluster-of-buildings level. In this market, the peak demand limit is represented by a virtual generator with a constant marginal cost. Numerical simulation results in MATLAB environment show that the proposed method enables reduction in the peak electrical demand from the system based on the existing market framework.
