Abstract

Current transactive controls use marginal benefits and marginal costs to achieve an economic market efficiency during normal grid operations. Because operations during contingencies often are dictated by technical needs rather than pure economic criteria during normal operations, transactive mechanisms designed for normal economic operations cannot be applied directly for the contingencies. This paper presents one of the first attempts to develop a transactive mechanism to be used during grid contingencies. A distributed blackstart and service recovery is used as an example contingency to evaluate the performance of the proposed transactive mechanism. The performance of the proposed transactive mechanism is demonstrated for various usecases using a modified IEEE-123 node test systems. The simulation results demonstrated the proof-of-concept of applying transactive mechanism to enable distributed blackstart and service recovery by engaging the mix of blackstart capable and non-capable distributed energy resources (DERs).
