Description
Summary:In this paper, we developed an optimal planning model of distribution network expansion considering integrated demand response. In this model, both shift load and cut load were considered, together with the nonlinear response cost function. We used dist-flow model and piecewise linearization to convert non-linear mathematical relationships into linear expressions. Then a mixed integer linear programming (MILP) model is established, which can be solved directly by Gurobi or CPLEX. Finally, case studies showed that integrated demand response can effectively reduce the total cost of the system, delay power grid investment, and promote construction of renewable energy and its consumption. In addition, the formulation of different cost functions and response scales will also have different effects on power grid planning. In actual planning, adequate research and evaluation should be conducted on responsive resources.
