SMART CITIES 2016 - Smart cities e smart communities

RSE developed a mathematical model of a real HDN. The model is able to describe the behaviour of the network when different parameters are varied, such as the heat demand or the on/off profiles of the generator machines. The aim of the model is to develop a system management able to optimize both the heat production and the interaction with the electric network. The model will be able to define how to operate the network in order to minimize the heat losses and the primary energy requests and to optimise the management to provide support services for the electric grid.

In the context of a smart city, the heat district network (HDN) is interconnected with other networks, such as the electrical one. The production peaks of electrical energy, typical of renewable energies, can be absorbed by the heat network: if the production peak occurs while the demand is low, the electrical energy can be converted into heat by means of the heat pumps. In turn, if the heat demand is also poor, the thermal energy can be stored into the storage tanks and used when it is actually needed. The thermal storages, typical elements of a HDN, are very important for the synergies between the energetic networks since they allow to uncouple the production and the demand , giving flexibility to the system. The HDN can interact in a flexible manner with the electrical system for another reason: standing the heat supply, the heat network can put the electricity into the grid (cogeneration) or can absorb it (heat pump). Both arrangements, extend the possibility of the exchange with the electric network and determine a potential offer of services, very interesting but not exploited yet.
