A multi-period scheduling strategy for active distribution network with efficient utilization of renewable energy
Nowadays, the active distribution network (ADN) is facing great challenges on safe operation and coordinated scheduling.To resolve these issues, a novel active-reactive coordination scheduling strategy for ADN is proposed.Firstly,based on the second-order cone relaxation (SOCR) method, the power flow equations are convexized and relaxed to transform the original model into mixed integer second-order cone programming (MISOCP).Then, on-load tap changer (OLTC) and capacitor banks (CB) are accurately linearized, so the model is converted to 0-1 MISOCP problem.Finally,compared with the existing strategies, numerical tests on the modified IEEE 33-bus test system demonstrate that on the premise of realizing the maximum utilization of DG, the proposed strategy can also achieve the purposes of energy-saving,loss reduction and improvement in voltage level and the utilization of ESS.
