A robust active distribution network defensive strategy against cyber?attack considering multi?uncertainties

A robust defensive strategy for active distribution networks considering multi-uncertainties and island restoration is studied. Firstly, the authors take triple uncertainties into consideration, that is, attack strategy, amount of wind power generation solar irradiation. Next, a trilevel defender-attacker-defender (DAD) two-stage mathematical model established to make full use energy storage support capacity reduce load shedding. The first stage pre-allocate resources, second dispatch emergent resources in worst scenario minimize Using column constraint (C&CG) algorithm solve model, original problem converted min main max-min sub-problem. non-convexity sub-problem relaxed by using order cone programming (SOCP) max according strong duality theory. Solving with returned cuttings iteratively. simulation results show proposed method effective can adapt multi-uncertainties.
