Abstract
To solve the problem of wind power accommodation, this paper proposed a coordinated wind power accommodating dispatch model based on combined electricity and heat system with the perspective of decoupling thermoelectric coupling constraints and enhancing the adjustment capacity of the power system. Firstly, this paper introduced the working principles of wind power characteristics and combined heat and power (CHP), the basic operating principles of the consumption of wind power curtailment using thermal storage. Secondly, the coordinated wind power accommodation dispatching model was established due to the regulations mentioned above. Thirdly, the main problem was divided into two sub problems by Benders decomposition, which are power and thermal dispatching, and then the optimum solutions which meet the constraints of each sub problem was solved using Interior point. Finally, the whole dispatching planning of CHP was obtained. Case study verified that, the proposed model is effective.
