The Optimal Energy Flow of Combined Heat and Power Systems Considering Users' Comfort

Combined heat and electric power energy networks are common as multi-energy systems and its optimal operation is a hot topic. The goals of this manuscript is to achieve the optimal heat and power flow for the coupling network with tree-topology heat network and DC power network. The study aims to minimize the total deviations between user setting points and building indoor temperatures, decrease total energy consumption and cost. An optimization model is proposed using a steady-state method. The effectiveness of this method is proved by simulation results. Optimal operational schedule is obtained which can considers the complexity of the combined heat and electric networks.
