Distribution network capacity support from flexible smart multi-energy districts

This paper explores from a techno-economic perspective the value of increasing distribution network capacity via Demand Side Response (DSR) services provided by smart multi-energy systems enabled by an intelligent information platform (i.e., the District Information Modelling and Management for Energy Reduction (DIMMER) platform under development in the homonymous European project). More specifically, the potential of smart multi-energy systems comprising gas boilers, Electric Heat Pumps (EHP) Combined Heat and Power (CHP) and a smart information platform to provide distribution network capacity is explored. For this purpose, a multi-energy district operation optimization approach coupled with a distribution network planning framework is proposed. The district operation model identifies the behavior of end-users who may aim at minimizing their energy costs and/or trade capacity with DNOs. The network planning framework calculates the value for DNOs from additional network capacity provided by customers. The methodology is illustrated via a real UK multi-energy district at the University of Manchester and the relevant electricity, heat and gas networks. The results highlight that the flexibility inherent in multi-energy systems can provide significant economic benefits for both end-users and DNOs.
