Participation of Grid-Connected Energy Hubs in the Energy and Reserve Markets

In this paper, optimal participation of the grid-connected energy hubs in the day-ahead energy and reserve markets is presented. The proposed scheme includes objective function that is minimized the difference between flexibility cost of hubs and their revenue in these markets. Also, this problem is constrained to power flow equations in the electrical, gas and heating networks, technical and reserve limits of these networks, and operation model of hubs including different sources and active loads. In the following, the stochastic programming is used to model the uncertainties of load, market price, networks reserve demand, renewable generation power, and energy demand of mobile active loads. Finally, by implement of the proposed scheme on the standard test network, the obtained numerical results confirms the capabilities of this scheme in the improvement of economic and flexibility situation of energy hubs, and improving the operation situation of the energy networks.
