Abstract:

This paper presents the optimal participation of distribution networks and energy hubs in the day-ahead wholesale and retail energy markets. The proposed scheme is a two-objective optimization model. In one objective function, it minimizes the energy cost of electricity, gas, and heating network as private distribution companies in the mentioned markets. In another objective function, it minimizes the energy cost (equal to the difference between selling and purchasing energy) of hubs in the retail market. This scheme is subject to optimal power flow formulation in the mentioned networks, and the operation model of sources and active loads in a hub format. Then, the Pareto optimization based on the weighted functions method according to the fuzzy decision is used to achieve the optimal compromise solution. Finally, by implementing the proposed scheme on a system test, the obtained simulation results confirm the capabilities of the scheme in improving the economy of energy hubs and the economic and operation situation of the mentioned networks.
