Embodiment Construction
[0017] Please check figure 1 , a distribution network ultra-short-term planning method for smooth switching of multiple operating modes, which includes the following steps:
[0018] In step 1, the distribution network is decomposed into several small-scale and mutually independent micro-grids according to the transmission lines of the distribution network; in this embodiment, the distribution network forms each micro-grid with new energy in units of stations. For example, taking each 10kV to 400V transformer station as a node, the line under a 10kV to 400V transformer is a microgrid with new energy in it.
[0019] Step 2, collect the information of each energy node and load node on the distribution network line, predict the load curve of the microgrid in a future cycle in the short term according to the historical load, and predict a future cycle (the cycle The duration can be set as the power generation curve of new energy (photovoltaic, wind power, hydropower) within seven ...
