Abstract:

With the growth of the economic level, the proportion of electricity consumption in buildings continues to increase. Optimizing building energy management strategies can effectively enhance energy conservation and reduce emissions. In commercial building loads, air conditioning loads and electric vehicles loads account for a large proportion of energy consumption. Therefore, a smart commercial building energy management model considering building thermal inertia and incorporating electric vehicle integration was proposed, with the behavioral characteristics of electric vehicles modeled via Monte Carlo simulation. Based on the thermal capacitance-resistance model, a building thermal dynamic balance equation was established. Scenario-based stochastic programming was adopted to establish a smart commercial building energy management model, and Conditional Value at Risk (CVaR) was introduced to improve robustness. The results of case studies showed that considering building thermal inertia could reduce the operating costs of air conditioning loads by 9.7% and increase revenue by 1.4%. Although CVaR reduces the operational risks of buildings, it also lowers their comprehensive expected returns.
