### The Impacts of Equivalent Thermal Resistance on Cooling Systems  
The impacts of the equivalent thermal resistance \(D\) on cooling systems are analyzed. According to the characteristics of different cooling buildings, the equivalent thermal resistance \(D\) is taken as 1 and 3, respectively. Taking the industrial area as an example, the cooling load curves and indoor temperature curves under different equivalent thermal resistance \(D\) are demonstrated in Figure 11. The correlation coefficients between the output of renewable energy and the cooling power under different equivalent thermal resistance are shown in Table 10.

volatility of renewable energy are given. Finally, an actual distribution system in Jianshan District, Haining, Zhejiang Province of China was used to demonstrate the effectiveness of the proposed coordinated dispatching model of integrated energy systems. The simulation results show that it is conducive to consuming the excess renewable energy and suppressing the volatility of renewable energy by improving the penetration rate of EVs, tie line capacity, equivalent thermal resistance, and adjustable heating duration, and properly releasing the PMV restriction and the charging power restriction of EVs.  
It should be mentioned that the model of this paper could be further studied under the following conditions: (1) A more detailed model of the heating network could be considered, including heating delay and loss, etc.; (2) The cost of tie lines could be considered to find the most suitable tie line capacity; (3) The distribution characteristics of EVs in various functional areas could be changed through the factor of electricity price to achieve more optimized dispatching without improving the penetration rate of EVs.
