“…The mathematical model of cooling load description is not given in the data driven method. Based on the input variables of historical data (e.g., heat source, environmental parameters and occupancy), the nonlinear dynamic model of cooling load under various disturbances is established by mixed integer linear program [ 41 ] and deep reinforcement learning [ 42 ].…”

“…As discussed in the literature review and from Table 1, at the time of writing, most urban energy systems modelling focuses on the provision of some energy service demands within heating, cooling, transport, and electricity for appliances; or uses coarse spatial resolutions such as integrated assessment models, which model national or regional scales (such as the MARKAL model [34], the ESME model [50] or the TIMES model [24]); or focus on specific technologies or on specific energy service demands (for example, Chiam, Easwaran, Mouquet, Fazlollahi, and Millás [51] optimise the operation of a district cooling network; del Hoyo Arce, Herrero López, López Perez, Rämä, Klobut, and Febres [52] model district heating and cooling; Pye and Daly [25] focus on urban transport; and Liu, Ho, Lee, Hashim, Lim, Klemeš, and Yee Mah [53] model distributed generation for supplying service demands for heat and electricity). No modelling framework exists that simultaneously includes the demand for heating, cooling, transport, and electricity for appliances, at a fine spatial resolution, and taking into account the trade-offs between supply, network infrastructure, and end-use technologies for all the aforementioned energy service demands simultaneously.…”

“…These statistics are even more valid in regions with tropical climates [5]. For instance, the percentage of energy used for space cooling in Mumbai (40%) is nearly as twice as that of London (20%) [6].…”

“…Moreover, it has to be considered that the temperature difference between the supply water temperature and the return water temperature for DCSs is usually around 8 • C, while in district heating systems the difference is generally higher than 40 • C [3]. Additionally, the tendency to be cautious in the design phase leads often to oversize DCSs, thus resulting in equipment underutilization, which is detrimental for energy efficiency [6]. For all these reasons, DCSs show an increase of the piping system cost and of the required pumping energy respect to district heating systems [3].…”
