Energy hub systems integrate various energy sources and interconnect different energy carriers in order to enhance the flexibility of the system. In this paper, a cooperative framework is proposed in which a network of energy hubs collaborate together and share their resources in order to reduce their costs. Each hub has several sources including CHP, boiler, renewable sources, electrical chiller, and absorption chiller. Moreover, energy storages are considered for electrical, heating, and cooling systems in order to increase the flexibility of energy hubs. Unlike the methods based on Nash-equilibrium points, which find the equilibrium point and have no guarantee for optimality of the solution, the employed cooperative method finds the optimal solution for the problem. We utilize the Shapley value to allocate the overall gain of the hub’s coalition based on the contribution and efficiency of the energy hubs. The proposed method is modeled as a mixed integer linear programming problem, and the cost of network energy hubs are decreased in the cooperative operation, which shows the efficiency of this model. The results show 18.89, 10.23, and 8.72% improvement for hub1, hub2, and hub3, respectively, by using the fair revenue mechanism. [less ▲]

This discussion paper is intended to present the range of optimisers developed in the SynErgie project and to go into more detail on the methodological aspects. In this discussion paper, a distinction is made between optimisers on the company platform and on the market platform. On the company platform, the goal is to ensure optimal operation of the plants, so that in addition to energy, other operational key figures are included in the analysis. These include various optimisers from production planning and control (PPC), which, in addition to energy costs, also track logistical target variables, such as the on-time delivery of products, as key figures. In addition to the production systems, the facilities of the technical building equipment (TGA) are also optimised on the company platform. Furthermore, within the discussion paper, we differentiate between energy-oriented and energy-flexible optimisation. Energy-oriented optimisation, pursues the goal of minimise energy costs, uses information from the energy markets, such as electricity price forecasts. With flexible optimisation, for example, flexibilities are determined or scheduled, which can then be transmitted to the market. The discussion paper also deals with the optimisation services of the optimisation services of the market platform, which determines the optimal marketing opportunity for the determined. The optimiser calculates the optimal time for different markets in order to maximise the proceeds of the maximise the revenue of the flexibility offered or minimise the costs. Should a flexibility provider decide to use a service to take over the marketing of his flexibility measure, information on the flexibility is transmitted between the flexibility is transmitted between the service and the company in order to be able to implement the measure in the company.
