ADMM-Based Multiperiod Optimal Energy Flow of A Regional Integrated Multi-Energy Microgrid

Abstract

As the further development of regional integrated multi-energy microgrid, the management of microgrid operators is getting more difficult because of different interest parts and data privacy preservation. Thus, an ADMM-based multiperiod optimal energy flow (MOEF) model is presented in this paper, which is meaningful to research collaborative operation scheduling of multi-energy microgrid. Since the MOEF model considering constraints of multi-energy networks and energy conversion units are highly nonlinear and nonconvex, a second-order cone relaxation and incremental linearization method are adopted to mathematically transform it into a solvable mixed integer second-order cone programming (MI-SOCP). A modified regional integrated multi-energy microgrid case is evaluated to demonstrate the effectiveness of the proposed model and method.
