Enable a new experience of park energy storage, and FGI dynamic load optimization leads the era of intelligent electricity consumption
1.Background
Industrial and commercial energy storage as a typical application of distributed energy storage system in the user side, while improving the consumption rate of clean energy, but also reduce power transmission losses, can effectively accelerate the energy transformation and the realization of dual-carbon goals. With the continuous deepening of the electricity price policy, the promulgation of power demand response policies in most provinces and cities across the country, and the continuous decline in the price of lithium battery raw materials and other favorable factors, the industrial and commercial energy storage application scenarios have also been further verified, and the dominant position of the market has become increasingly clear.
2.Traditional industrial and commercial energy storage charging and discharging scheme
In the case of simple, stable and small changes in the load of the original industrial park, the use of traditional time strategy to control the charge and discharge time and power of industrial and commercial energy storage can basically meet the needs of users.
However, as the user's power system configuration changes, and higher economic benefits are demanded. The industrial park gradually increases the photovoltaic power generation system, distributed wind power generation system, adjustable and controllable load, etc., resulting in a greater change in the load of the industrial park, sometimes the power supply increases the load becomes smaller and needs to be charged, and sometimes the power supply reduces the load and needs to discharge, but also consider the user's basic capacity (demand) electricity and other factors. Simple time plan charging and discharging can no longer meet the needs of market development.
3.FGI Industrial and Commercial energy storage solutions
There are many equipment in traditional industrial parks, which have the characteristics of large power consumption, long load time and large energy consumption of equipment. If a large amount of renewable energy is used, energy storage systems are needed to adjust the balance of supply and demand.
In the "industrial park + energy storage" mode, the energy storage system can store the excess power of the photovoltaic system and release it during peak hours, which can not only ensure the stability of power consumption in the park and relieve the pressure of the grid, but also provide backup power in emergency situations to ensure the normal operation of the park. At the same time, the price difference of industrial parks in China is high, which is suitable for peak valley arbitrage of energy storage projects.
4.FGI industrial and commercial energy storage typical application cases
The user of an industrial zone in Wenzhou, Zhejiang Province is mainly engaged in the processing and manufacturing of automotive parts. In order to reduce the cost of electricity, the park owner added a 2MW photovoltaic power generation system; At the same time, in order to solve the problem of electric vehicle charging for employees, 80kW electric vehicle charging pile is configured; In order to ensure market demand such as emergency delivery of market orders, the park owners have added flexible dynamic production lines. In addition to the normal production load, office load and emergency production load of park owners, the uncontrollable factors of power load of park owners are gradually increasing.
In order to solve the power system demands of the above users, and cooperate with the user's photovoltaic power generation, flexible load changes, etc., our company through the on-site demand analysis, the user's distribution situation combing, gives the use of industrial and commercial energy storage for power load dynamic real-time tracking solutions.
Six sets of 100kW/215kWh industrial and commercial energy storage products are configured for the user, and a bus cabinet is configured to directly access the 400V low-voltage side distribution bus. By using the characteristics of industrial and commercial energy storage system as a power system reservoir, docking the park owners' photovoltaic power generation system, electric vehicle charging system, flexible production line load, production power load, etc., through the means of information and high-speed to open up and sense all power load changes, and then real-time tracking analysis, dynamic change the industrial and commercial energy storage charging and discharging state. Charge and discharge power, etc., gradually optimize the electricity economy of users, reduce the cost of electricity for owners, and increase the overall income of owners.
5.Characteristic of project
Industrial and commercial energy storage systems open up the flexibility of the power system for users. According to the demand for electricity production, the access of new energy sources such as photovoltaic power generation and distributed wind power can be continuously adjusted.
Industrial and commercial energy storage systems through flexible load tracking algorithms and technologies, can be continuously selected in the "low buy high sell" strategy, reducing the cost of electricity for owners.
The dynamic load tracking strategy of industrial and commercial energy storage systems can meet the changing needs of users, and truly realize the purpose of "on-call, source-on-load".
The dynamic load tracking strategy of industrial and commercial energy storage is realized, and users can choose capacity electricity price and demand electricity price more flexibly, and layout power payment mode and basic electricity price more reasonably, thus improving user benefits.
6.Value gain
The bottleneck of industrial and commercial storage as a single role of peak cutting and valley filling is solved, and the "gorgeous turn" from passive equipment application to active optimization strategy is completed.
Through the high-speed informatization of industrial and commercial energy storage, photovoltaic power generation system, distributed wind power system, charging pile system, production load, flexible load and other systems, the situation of "each fighting for itself and fighting alone" is solved.
The industrial and commercial energy storage system can cope with the application scenarios of dynamic changes in the charge and storage of the source network, achieve strategy optimization, and expand the application value of industrial and commercial energy storage.
Industrial and commercial energy storage system in the face of industrial and commercial park owners demand for electricity, provides a flexible solution, not only to meet the existing load, but also compatible with load changes.
