Embodiment Construction

[0085] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0086] Step 1: The schematic diagram of the optimal operation method and system network topology diagram of the active distribution network including low calorific value power generation and wind-solar distributed new energy in this embodiment is as follows figure 1 shown. Photovoltaic power generation, wind power generation, and energy storage equipment are connected to the grid busbar through inverter devices, and electric loads are connected to the grid busbar through step-down transformers. Low calorific value power plants are directly connected to the grid busbar. The energy has two effects on the fluctuation of the bus voltage. Low calorific value generating units,...

Description

technical field [0001] The invention relates to the technical field of multi-energy systems, in particular to a distribution network optimization operation system and method including low calorific value power generation and distributed power sources. Background technique [0002] With the development of today's social economy and technology, the power system is developing in a diversified, efficient and clean direction. my country is actively building clean energy power plants including wind energy, solar energy and other high-utilization power generation equipment composed of low calorific value fuel units. And achieved phased results. However, there are many problems in the new energy power generation at the present stage, and the access technology of low calorific value power generation devices is not mature enough. New energy such as wind energy and light energy have the characteristics of randomness and instability, which usually bring a certain burden to the power sys...
