Planning of multi-hub energy system by considering competition issue

Energy hub concept has been emerged as a suitable tool to analyze multi-carrier energy systems. Deregulation and increasing competition in the energy industry have provided a suitable platform for developing the multi-agent energy systems. Planning of energy hubs considering the competition between the hubs has not been sufficiently addressed, yet. A model has been proposed in this study for planning of a multi-hub energy system considering the competition between the hubs. The hubs are interconnected via an electric transmission system. A linear model has been developed to determine the optimal planning/operation strategy for energy hubs in a multi-period planning horizon to meet the heat and electricity demand for the defined load zone. The problem has been formulated and solved using Karush-Kuhn-Tucker (KKT) conditions. The proposed model has been applied to 3-Hub and 5-Hub energy systems. The effect of renewable generation and storage system has also been evaluatedIt has also been observed that inclusion of renewable generation or storage technologies can reduce the conventional electricity generation capacity by 63 percent in HUB2. © 2021, Aalborg University press.
