Meanwhile, the existing planning models neglect to consider renewable energy uncertainty methods, specifically concern the renewable energy confidence, also the future possible scenarios, thus a confidencebased scenario cluster method is presented. The construction of the paper is, a novel GNLS (Generator, Network, Load, energy Storage)-Co planning model is proposed. First, a confidence-based scenarios cluster is built which can reflect uncertainties by clustering and analyzing wind, solar and load. Second, the proposed model focuses on load and energy storage co-planning, in addition, relevant flexible indices are used to assess the model. Last, the GNLS-Co planning model is built as a bi-level stochastic model on a continuous-time scales. The model is solved by benders decomposition algorithm. The method in this paper is validated by an IEEE RTS 24-bus and a real test system in China, to demonstrate the reduction of renewable energy curtailment and optimize economic in power system planning.
