Embodiment

[0055] A method for dispatching power supply energy of multiple power users in the environment of lack of regional power grid power supply, such as figure 1 shown, including the following steps:

[0056] S1: Obtain the park power consumption data of multiple power users;

[0057] The multi-power user power optimal dispatch model includes a power outage loss model, an energy storage configuration cost model, and a user dissatisfaction model. The schematic diagram of the energy flow and information flow of power sharing and management among multiple power supply users under the environment of power loss is as follows: figure 2 shown. In the multi-power user area under the environment of lack of power supply, some parks have excess power consumption at a certain moment, while others have insufficient power consumption. At this time, power sharing between parks can be carried out to achieve effective energy use. Multiple parks energy management system (MEMS) is a control syste...

Abstract

The invention relates to a multi-power-user power supply energy scheduling method in a regional power grid power supply lack environment. The method comprises the following steps: S1, acquiring park power consumption data of multiple power users; s2, building a multi-power-user electric energy optimization scheduling model in a power supply lack environment; and S3, solving the electric energy optimization multi-target optimization model of the multi-electric power supply users in the power supply lack environment, and obtaining a scheduling scheme. Compared with the prior art, the method can effectively promote the effective utilization of the limited electric quantity when the power supply of the power grid is lacked, and improves the balance of the micro-grid in the island state and the power utilization economy of the user.

Description

technical field [0001] The invention relates to the field of power dispatching, in particular to a method for dispatching power supply energy of multiple power users under the environment of lack of power supply in a regional power grid. Background technique [0002] At present, energy optimal scheduling is mainly energy scheduling when the electricity is sufficient in the case of grid connection. In the existing technology, when the energy is sufficient, it can ensure the sustainable power supply of loads in all time periods, and consider the loads of factors such as time-of-use electricity prices and peak-shaving and valley-filling. Work time optimization scheduling strategy. There is also a form of optimizing strategies based on renewable energy utilization, network loss, and user satisfaction through dispatching and controlling distributed power sources, energy storage devices, and flexible loads. [0003] However, the existing technology only considers dispatching load...
