Energy transition is a key driving force for the development and progress of human civilization, with green and low-carbon growth now a global trend. The new energy revolution has attracted worldwide attention and has become a critical pathway for countries to achieve green and sustainable development.

In recent years, global energy supply has been under pressure and electricity costs have risen sharply, with frequent power outages and power restrictions occurring in some countries and regions. The emergence of new power systems, coupled with the ongoing energy transition and the rapid proliferation of renewable energy, has driven a continuous increase in the demand for energy storage to ensure reliable daily electricity supply. In response to the vast opportunities in the energy storage market, many companies have seized the moment and launched a variety of energy storage products.

Energy storage technology functions like a “power bank,” enabling flexible storage and discharge of electricity—storing surplus energy when available and releasing it when needed—thus ensuring uninterrupted and stable power supply.

Energy storage systems can be connected to the grid as independent units, providing functions such as peak shaving, valley filling, and reactive power compensation. They can also be integrated with renewable generation to form wind-solar-storage systems, smoothing the power of renewable energy grid connection. Furthermore, energy storage systems can be co-located with wind, solar, and other renewable generation at load centers to form microgrid systems, thereby improving energy utilization efficiency, enhancing power quality, increasing supply reliability, and supporting sustainable and environmentally friendly energy practices.

一、CEEG Provides Customized Solutions for Different Application Scenarios

（一）Regions with Curtailment of Renewable Power Generation

Solution Features:

1、 AC network configuration for easy system integration.

2、Reduce solar and wind curtailment, improving economic benefits.

3、 Enhance stability and predictability of grid-connected generation.

4、Improve planning capability for grid dispatch.

（二）User-Side: Commercial & Industrial (C&I) Energy Storage Solutions

（三）Energy Storage Solutions for Photovoltaic Power Plants

Solution Principle:

Photovoltaic is intermittent, fluctuating, and difficult to predict. Large-scale integration of PV inevitably increases grid regulation challenges and leads to significant curtailment of solar energy. Adding energy storage to PV power stations effectively addresses these issues by storing excess electricity and releasing it during periods of low generation or peak demand to smooth power output, thereby making up for the unstable power generation of new energy.

Solution Advantages:

1、Reduce solar energy curtailment and effectively address energy utilization challenges.

2、Smooth random fluctuations in output, improving power quality.

3、 Enhance the accuracy of power generation forecasting.

4、Enable PV plant energy storage to participate in ancillary services, improving the output characteristics of the PV plant.

（四）Energy Storage Solutions for Wind Power Stations

Solution Principle:

Wind power is intermittent and fluctuating, and large-scale grid integration can impact the stable operation of the power system, increasing the demand for regulation resources. The introduction of energy storage systems provides a buffer for wind power integration, helping to smooth output fluctuations and facilitate energy dispatch. It can dynamically absorb energy quickly and release it at the right time, improving power quality, enhancing wind power controllability, and increasing overall power system stability.

Solution Advantages:

1、Reduce wind curtailment and improve economic benefits.

2、Smooth random output fluctuations, enhancing power quality.

3、Improve power forecasting accuracy.

4、Energy storage for wind farms.

二、CEEG’s all-in-one energy storage and boost converter system — A Breakthrough in All-in-One Design

Keeping pace with industry trends, CEEG has strategically advanced into the “New Energy + Energy Storage” sector and launched its all-in-one energy storage and boost converter system solution.

Product Features:

1、Turnkey Solution

Integrates PV inverter, transformer, and switchgear into one unit. Factory-commissioned as a whole, reducing on-site installation and commissioning time.

Containerized housing, requiring no special lifting tools, making transportation and installation convenient.

2、Strong Environmental Adaptability

Strong corrosion resistance: Container-type enclosure made of high weather-resistant steel, offering superior corrosion resistance compared with ordinary carbon steel.

Thermal insulation: Internal insulation panels provide excellent fireproofing, heat insulation, and temperature retention.

Ventilation and cooling: Specially designed air inlets effectively prevent dust and sand ingress.

3、 High Reliability and Safety

Equipped with epoxy resin cast dry-type transformer, a flame-retardant product with no risk of explosion or fire.

Dry-type transformer certified by the National Transformer Quality Supervision and Inspection Center, passing C2, E2, F1 tests.

4、 Low Investment, High Return

Compared with the conventional “inverter room + PV box-type substation” setup: Investment reduced by 15%–20%.

Installation foundations reduced from two to one. Installation and commissioning time reduced by 50%. The inverter and transformer are connected with copper busbars, which saves the connection cables between the inverter room and the PV box-type substation. The optimized structure saves two low-voltage switchgears between the inverter and the transformer.

5、Flexible and Diverse Solutions

Designed fully in line with actual customer needs, providing customized and satisfactory one-stop solutions.
