Distributed New Energy (Energy Storage) Solution

Distributed new energy (energy storage) has been widely used in industrial parks, business circles, office buildings and other large-scale industrial and commercial high-energy-consuming units. The combination of distributed photovoltaic and energy storage further improves the economy of distributed energy.

Peak cutting and valley filling

Through the valley charging energy storage, peak discharge energy supply, reduce the cost of electricity for enterprises or parks, for customers to save electricity.
Dynamic capacity increase

When the short-term power consumption is greater than the transformer capacity, the energy storage system will discharge quickly to supplement the capacity gap, meet the load power demand requirements, and avoid the power capacity increase project.
Power Trading

In the power market trading platform, combined with load forecasting and real-time voltage for short-term power trading, to maximize revenue.
Off-grid standby power

When the power is interrupted, it provides uninterrupted short-term power supply for important loads to reduce the economic loss caused by sudden power failure of the load.
Demand-side response and ancillary services

Perform demand-side response based on grid demand, or participate in ancillary services market transactions to perform peak and frequency modulation tasks.

Smart Microgrid

Can configure wind, light, firewood, storage and other energy forms as needed to provide power supply for areas without electricity and weak current, provide power support for temporary power consumption scenarios, or guarantee power supply for important equipment in the plant area, or participate in power market transactions as needed to realize comprehensive energy management, with economic, security and green environmental protection benefits.

Photovoltaic storage mode

Photovoltaic power generation is preferred for its own use, and the remaining electricity is stored in the battery. When the photovoltaic energy is insufficient, the energy storage will supply power to the load;
istributed photovoltaic self-use, residual electricity to participate in power trading, when the electricity price is low stored in the battery, when the electricity price is high for power trading.
Photovoltaic storage diesel mode

Photovoltaic is preferentially supplied to the load, and the remaining electricity is stored in the battery. When the photovoltaic energy is insufficient, the energy storage will supply power to the load first, and the diesel engine will supply power to the load if the energy is insufficient.
Mixed mode of firewood storage

Energy storage can quickly respond to changes in load power, making the diesel engine always maintain the best efficiency range.
Emergency power supply (standby power) mode

When the mains power is cut off, it will automatically switch to off-grid load to ensure that the load does not lose power. At the same time, it supports off-grid black start, which can ensure emergency load power supply.

Light Storage and Charging Scheme

Be determined according to the scenario requirements. The DC coupling scheme and flexible converter can reduce the link of power conversion, improve the efficiency by more than 3%, and increase the income.

Light Storage and Charging Scheme - Energy Storage Solution

Configuration

Modular design, can be used in combination, free expansion. The combination of various ways, support a variety of energy access, optical storage, storage charge, optical storage charge mode.optional high-power V2G function.
Lower cost

Shares the converter interface with the grid, and the energy routing is realized by software.
BMS and PCS deep integration, further reduce cost efficiency, improve performance.
More efficient

Reducing energy conversion links and cable losses, the cycle efficiency of the green electric direct charging system is increased by 2%. The flexible converter uses silicon carbide devices to increase the cycle efficiency by more than 1%. The group string scheme avoids circulation and improves utilization.
Security

System is simple and has fewer failure points;distributed modular architecture, fault removal can be divided into areas to ensure the overall utilization.
