Optimal Control of Energy Systems in Net-Zero Energy Buildings Considering Dynamic Costs: A Case Study of Zero Carbon Building in Hong Kong

Net-zero energy buildings coupled with multiple demands on the load side, which utilize renewable to a larger extent, are an effective way consume distributed capacity in situ and need face operational challenges brought by uncertainty of while meeting different demands. To this end, paper proposes Dynamic Cost Interaction Optimization Model (DCI-OM) Electric Vehicle Charging Station (EVCS) based dynamic cost (i.e., oil price, electricity price) considers proportion be consumed. In model, optimized cooling demand dispatch scheme is given daily operating as objective function. Using Zero Carbon Building Hong Kong, China, example, simulations performed for typical days 21 March, June, 22 September, December) four seasons throughout year. The results show that electric response DCI-OM achieves peak valley reduction according reduces original costs ensuring customer’s comfort needs within acceptable limits. scheduling meets reducing cost.
