Abstract

The utility model provides a system for monitoring the charging and the discharging of an energy storage battery accessing to a power network, which comprises a power network load forecasting module, a dispatching and monitoring module in circuit connection with the power network load forecasting module, a power network accessing module in circuit connection with the power network load forecasting module, a battery management module in circuit connection with the dispatching and monitoring module and the power network accessing module, and the energy storage battery in circuit connection with the power network accessing module and the battery management module. According to the utility model, different charging-discharging control strategies are adopted according to different power network loads and peak-valley differences, the power supply load requirement is transferred from a peak value moment to a load valley moment, and the electric energy is supplied to users under the circumstances of forced power failure or power interruption, so the operation stability of the system is strengthened, the quality of the electric energy is improved, and the stabilizing ability of the power network is further improved.

Description

The energy-storage battery that inserts electrical network is carried out the system of charge and discharge monitoring

Technical field

The utility model relates to a kind of system that the energy-storage battery that inserts electrical network is carried out charge and discharge monitoring.

Background technology

In recent years, the China Power load growth is rapid, the contradiction of power supply and demand has appearred in many areas, particularly during meeting the summer in kurtosis winter, peak load often is subjected to the restriction of generating capacity and power grid security, need rationally to arrange electric load to make full use of electric energy, alleviate electrical network pressure and battery energy storage system is one of important component part of current network system, the excellent means of more effective management, control, supervision, dispatching of power netwoks operation can be provided for electrical network.And for better function and the responsibility of bringing into play the battery energy storage background monitoring system, improve the efficiency of management, must have cover system complete, science, handled easily, that be easy to control and support, could satisfy to greatest extent the user to supervision, guidance and the control of dispatching of power netwoks situation, make operation of power networks efficient, stable more.

The utility model content

A kind of system that the energy-storage battery that inserts electrical network is carried out charge and discharge monitoring that the utility model provides, at obstructed network load and peak-valley difference, adopt the different control strategies that discharges and recharges, to transfer to load valley constantly constantly from peak value to the supply load demand, under the situation of forcing power failure or power failure, provide electric energy to the user, thereby the stability of enhanced system operation and the raising quality of power supply further improve stabilization of power grids ability.

In order to achieve the above object, the utility model provides a kind of system that the energy-storage battery that inserts electrical network is carried out charge and discharge monitoring, this system comprises the network load prediction module, circuit connects the dispatching and monitoring module of described network load prediction module, circuit connects the electrical network access module of described network load prediction module, circuit connects the battery management module of described dispatching and monitoring module and electrical network access module, and circuit connects the energy-storage battery of described electrical network access module and battery management module.

The utility model is gathered various batteries, electric network data, be convenient to electric administrative department and in time grasp battery electric quantity, battery charging and discharging ability, various data such as network load and information are by carrying out Treatment Analysis to information, form control strategy, in time issue various control command, the electric network informations of discharging and recharging, to the electrical network transmission of electric energy, this mode helps to reduce the loss of system's electric power transmission network when the network load peak value, load is implemented peak load shifting, thus the economic benefit of obtaining.And can be the policymaker and carry out medium-term and long-term macro-management, planning, scheduling foundation is provided.
