Integrated Wind-Solar-Storage Commercial System

Designed specifically for scenarios such as grid support, commercial and industrial power supply, and microgrid construction, the integrated wind-solar-storage system combines wind power generation, solar power generation, and energy storage functions. Centered on "flexible dispatch, high integration, and digital twin", it offers advantages such as safety and reliability, as well as high efficiency and energy conservation. It can not only make up for the intermittent nature of wind and solar energy but also provide stable power support for the grid and user side, meeting the energy management needs of various scenarios.

Core Advantages: 7 Key Features to Address Energy Management Challenges

1. Flexible Energy Dispatch: Multi-source Coordination and On-demand Allocation

The system can intelligently coordinate the energy flow between wind power, solar power, energy storage units, and the public grid to achieve "on-demand dispatch":

• When wind and solar power generation is abundant, it prioritizes meeting the load's electricity demand and stores the excess power in the energy storage unit.

• When wind and solar power generation is insufficient or during peak electricity consumption, the energy storage unit quickly discharges to supplement energy or automatically draws power from the grid.

• Supports "off-grid / grid-connected" dual-mode switching. In off-grid scenarios, wind + solar + storage units supply power collaboratively. In grid-connected scenarios, it can cooperate with the grid for regulation, adapting to different energy demands.

2. Highly Integrated Design: Simplified Structure, Cost Reduction, and Efficiency Improvement

It adopts a "PV and ESS integrated" architecture, integrating photovoltaic inversion, energy storage management, and energy regulation functions into a single device. Compared to traditional split systems:

• Reduces more than 50% of external components, reducing equipment floor space (a single system saves 30% compared to split systems).

• Simplifies the installation process, eliminating the need for separate debugging of photovoltaic, energy storage, and inverter modules, reducing on-site wiring by 60% and shortening the deployment cycle.

• Reduces the complexity of later maintenance, making single-point fault detection more convenient and reducing operation and maintenance labor costs.

3. Digital Twin Control: Real-time Mapping and Precise Prediction

Equipped with an intelligent energy management system (EMS), it builds a "virtual mirror" of the system based on digital twin technology:

• Based on historical data and algorithms, it predicts the energy supply and demand trend for the next 24 hours and adjusts the energy storage charging and discharging strategy in advance (for example, based on meteorological data, it predicts weak sunlight and wind strength the next day and prioritizes energy storage on the current day).

• Supports remote cloud control, allowing adjustment of operating parameters through a computer or mobile phone, without the need for on-site monitoring.

4. Safe and Reliable Operation: Multi-layer Protection, Resilient to Risks

It builds a comprehensive safety guarantee system from equipment to the system, eliminating operational risks:

• Grid compatibility: When grid-connected, it complies with grid voltage and frequency standards, avoiding impacts on the grid.

5. High Efficiency Energy Conversion: Low Loss, High Transmission, and Increased Revenue

The system optimizes energy conversion efficiency at all stages, reducing energy loss:

• Both photovoltaic modules and wind turbines use high-efficiency power generation technologies, enhancing the capture rate of wind and solar energy.

• The inverter has high conversion efficiency, and combined with energy storage charging and discharging management strategies, it reduces energy loss during storage and release.

• The overall system energy utilization rate is ≥85%, and by adopting more advanced MPPT technology, it increases power generation by 15% to 20% compared to traditional wind-solar systems under the same wind and solar resources.

6. Long-life Energy Storage Assurance: Durable, Low Consumption, and Cost Reduction

The energy storage unit uses long-cycle-life battery cells, offering the following advantages: • The cycle life can reach over 5,000 times, and under normal use, the lifespan exceeds 10 years, reducing mid-term replacement costs.

• It supports deep charging and discharging (discharge depth ≥ 80%), with high utilization of energy storage capacity, avoiding the problem of "false capacity marking".

• It has self-maintenance functions, automatically balancing cell voltages, delaying capacity attenuation, and maintaining stable energy storage capacity over the long term.

7. Intelligent operation and maintenance early warning: Proactive detection, reducing downtime

The EMS system has fault early warning and self-diagnosis capabilities, reducing operation and maintenance difficulties:

• Real-time monitoring of component status, such as abnormal wind turbines, photovoltaic shading, and battery cell attenuation, and pushing early warning information in advance;

• Comes with a fault detection guide, clearly stating the cause of the anomaly and the solution steps, allowing non-professionals to handle it initially;

• Supports operation and maintenance data statistics, automatically generating power generation, energy storage, and fault reports, facilitating the optimization of operation and maintenance strategies.

Core Configuration: Multi-component coordination, building a stable energy system

The system achieves smooth operation of the entire chain from "power generation - energy storage - dispatch - output" through the efficient coordination of core components:

• Dual-source power generation unit: Wind power generation unit and solar photovoltaic modules work together, taking advantage of the complementary characteristics of wind and solar (solar power during the day and wind power at night or during windy periods), reducing the impact of intermittent single energy sources;

• Wind turbine controller: Adapted to wind power generation voltage, converting wind power into stable electricity, and also featuring voltage regulation capabilities to ensure the quality of electricity connected to the system;

• PV and ESS integrated equipment: Integrating photovoltaic inversion and energy storage charge and discharge management functions, uniformly regulating photovoltaic and energy storage electricity, simplifying the system structure;

• Intelligent Energy Management System (EMS): Acting as the "system brain", it is responsible for digital twin mapping, energy dispatch, safety monitoring, and operation and maintenance early warning, achieving full-process intelligence;

• Wide-range compatibility design: Supports a wide input voltage range (200V to 800V), with rated power covering 20kW to 50kW, and energy storage capacity of 50kWh to over 100kWh, adapting to different scale electricity demands.

Core Applications: 8 Scenarios, Empowering Grids and User Sides

1. Grid peak shaving and valley filling

   Responding to grid load fluctuations, during peak electricity consumption periods (such as afternoons in summer and nights in winter), the energy storage unit releases electricity, reducing the pressure on grid power supply; during off-peak periods (such as early morning), it stores excess solar and wind power or low-cost grid electricity, smoothing the grid load curve and assisting in stable grid operation.

2. Stable power output

   Compensating for the intermittency of wind and solar energy, through the energy storage unit's "peak shaving and valley filling", it ensures stable output voltage and frequency (three-phase AC 400V, 50/60Hz), directly supplying power to precision equipment (such as data centers, laboratory instruments), avoiding equipment failures due to voltage fluctuations.

3. Emergency backup power

   When the public grid suddenly experiences a power outage (such as due to natural disasters or line faults), the system can switch to "off-grid mode" within milliseconds, with the energy storage unit quickly releasing electricity, providing continuous power to critical loads (such as hospital ICUs, communication base stations, emergency command centers), avoiding significant losses caused by power outages.

4. Independent power supply in microgrids

   In remote areas without a grid (such as mountain villages, remote mining areas), the system can build an independent microgrid, generating power through the coordination of "wind + solar + storage", meeting the electricity needs of residents and production within the area, without relying on long-distance grid transmission, reducing grid construction costs.

5. Grid frequency and voltage regulation

   As an auxiliary service device for the power grid, the system can quickly respond to fluctuations in grid frequency and voltage (such as frequency deviations caused by sudden increases or decreases in wind power or photovoltaic power), adjust the charging and discharging power of energy storage, and compensate for changes in grid load in real time, helping the grid maintain frequency stability (50/60Hz ± 0.2Hz) and enhance grid resilience.

6. Energy conservation and cost reduction for industrial and commercial users

   In response to the pain point of "large peak-valley electricity price difference" for industrial and commercial users, the system stores low-cost grid electricity or surplus wind and solar power during off-peak hours (such as late at night) and releases stored energy during peak hours (such as during the day for production), replacing high-cost grid electricity and reducing enterprise electricity expenses. In some scenarios, electricity savings of 20% to 30% can be achieved.

7. Integration of renewable energy

   Deployed near large-scale wind and solar power stations, the system stores excess electricity generated by the stations (preventing "abandonment of wind and solar power") and supplies the electricity to the grid when needed, improving the utilization rate of wind and solar energy and contributing to the achievement of the "dual carbon" goals. At the same time, it creates additional revenue for the power stations.

8. Protection of sensitive loads

   For loads with high requirements for power stability (such as semiconductor production lines and precision testing equipment), the system provides "uninterrupted power support". It continuously monitors the quality of the grid and immediately switches to energy storage power supply without interruption if problems such as voltage sags or harmonics occur in the grid, ensuring that the loads do not shut down and reducing production losses.
