Research on Joint Planning Technology of Source-Network-Load-Storage Based on Typical Daily Scenarios

With the large-scale access of power electronics, the joint planning technology of source-network-load-storage is a new research hotspot. This paper proposes a joint planning method of source-network-load-storage based on typical daily scenarios. First, the historical data of original wind power, photovoltaic, electric vehicle charging stations and loads are preprocessed , use clustering algorithm to create typical day scenes of spring, summer, autumn and winter. Then, comprehensively considering investment costs and operation maintenance costs, a joint planning model of source-network-load-storage is established, the model is converted to convex based on the second-order cone relaxation theory. Finally, a typical daily scenario is used to simulate the distribution system example of Portugal 54 nodes. The consequence of example analysis displays that the combined planning model of source-network-load-storage can reduce the total cost of distribution system planning level year.
