FGI Industrial and commercial park storage new realm, dynamic expansion opens a new era of energy efficiency
1.Background
In the process of enterprise operation and development, the energy demand of many small and medium-sized enterprises will often rise. If the existing transformer capacity of the enterprise is difficult to match the current demand for electricity, then it is imperative to increase the power capacity. When the power load is too heavy, it will not only reduce the power efficiency, but also very likely to cause damage to electrical equipment, and even cause serious accidents such as fire.
2.Traditional expansion solution
Capacity expansion can be achieved by increasing the capacity of an existing transformer or adding a new transformer. If the capacity of the existing transformer has not reached its upper limit, it can be considered to connect a new transformer on its side to form a parallel operation, thereby increasing the total capacity.
The user needs to apply for transformer expansion to the power supply company, and then arrange relevant departments to review, and then replace or add transformers. The problem is that the application process is more complicated, time-consuming, and may lead to power outages affecting the normal production of users, as well as the economic cost of replacing the converter is higher.
3.FGI Industrial and Commercial energy storage solutions.
The user of an industrial zone in Hangzhou, Zhejiang province is mainly engaged in the processing and manufacturing of industrial packaging materials. The existing transformer has a capacity of 1250kVA, and the maximum load in the current production process is about 90%, and the power is about 1000kW; The user's new manufacturing equipment is 200kW, which has exceeded the capacity of the transformer. If the transformer is added, or the replacement of the transformer directly affects the normal production process of the user, and it takes a long time, the application is cumbersome, and the economic cost is relatively high; Our company through the on-site demand analysis, the user's power distribution situation combing, gave the use of industrial and commercial energy storage for dynamic capacity expansion solutions.
Four sets of 125kW/261kWh 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. Directly expand the user's load capacity to 1750kVA; The maximum load rate of the user is reduced to more than 70%, and more load space is reserved, making the user's electricity more safe.
4.Characteristic of project
Industrial and commercial energy storage systems can achieve dynamic expansion for users and flexibly adjust the changing needs of user loads.
Industrial and commercial energy storage systems can meet the configuration of different capacity needs of users through flexible configuration capacity, reducing the loss caused by shutdown.
Industrial and commercial energy storage systems can change according to the load of users, not only meet the needs of peak cutting and valley filling, but also meet the optimization strategy of capacity electricity price.
With the configuration function of industrial and commercial energy storage, users can choose capacity electricity price and demand electricity price more flexibly, and more reasonable layout of power payment mode and basic electricity price.
5.Value gain
The paper explores the solution of industrial and commercial energy storage system to cope with the change of power production load in flexible industrial parks, which can establish a good demonstration case for dynamic capacity expansion.
It realizes the solution that the user can decide the load capacity independently when the configuration of the user's power transformer is unchanged, and expands the solution of the power production load change.
Industrial and commercial energy storage systems provide capacity expansion solutions to cope with changing production loads, which can be a good demonstration application for the future promotion of microgrid application cases in off-grid mode.
The industrial and commercial energy storage system provides a good flexible configuration solution for the change of the owner's power load, and plays a role in application and demonstration.
