A bi-level co-expansion planning of integrated electric and heating system considering demand response

With the wide deployment of combined heat and power units, electric boilers, etc., system heating are coupled tightly, which necessitates expansion planning in a coordinated manner. Demand response (DR) is considered an effective method for augmenting flexibility, would lead to more beneficial strategy co-expansion strategy. Therefore, we develop bi-level model with DR constraints integrated minimize expenses on both investment operation. The upper level gives optimal energy facilities, while lower operation problems under given decision. Numerical simulation employed P6H8 demonstrate proposed model.
