Operation control method for integrated energy system containing hybrid energy storage

Abstract

The invention provides an operation control method for an integrated energy system containing hybrid energy storage, and relates to the technical field of energy scheduling. According to the actual operation condition of an energy storage device, a preset integrated energy system containing hybrid energy storage and comprising a distributed energy storage device, a distributed energy generation device and an energy conversion device is constructed, and the preset integrated energy system containing hybrid energy storage can be a virtual power plant or a virtual power plant. Detailed independent modeling is carried out on each device in the virtual power plant, energy balance constraint, hybrid energy storage constraint, device operation constraint and energy transmission network constraint are comprehensively considered for the hybrid energy storage comprehensive energy virtual power plant, and finally, maximum income and minimum energy loss are used as objective functions, and an optimal scheduling model of the hybrid energy storage integrated energy virtual power plant is established, and the electric energy conversion amount of each device in the distributed energy storage device is obtained, so as to compensate the random volatility and intermittency of the distributed energy through the electric energy conversion of the energy storage device.

Description

technical field [0001] The present application relates to the technical field of energy dispatching, in particular to an operation control method of an integrated energy system including hybrid energy storage. Background technique [0002] Energy is an important basis for the operation and development of the global society. For a long time, due to the excessive dependence of human beings on fossil energy with limited resources, it has caused environmental pollution that cannot be ignored. To cope with energy depletion and environmental pollution, clean energy such as electricity, natural gas and new energy are gradually moving from research to application. [0003] The distribution of new energy in different regions is uneven. For example, the areas with sufficient wind energy for power generation are mainly in the open areas such as northern plains and grasslands; the areas that can carry out photovoltaic power generation are concentrated in the plateau; the areas that can ...

Problems solved by technology

[0004] Under the existing technology, it is common to adjust the scheduling and distribution of power by laying the transmission network. However, the circuit network has a long setting cycle and cannot cope with sudden peak power consumption or other power consumption conditions.
