With the deepening of the "dual carbon" goals, zero-carbon industrial parks have emerged as pivotal platforms for energy transition and industrial upgrading. The integration of generation-grid-load-storage systems under high-energy penetration represents a critical pathway to resolving energy management challenges in these parks. The 2025 notice issued by three ministries on zero-carbon park construction explicitly requires parks to achieve near-zero carbon emissions through technological and managerial innovations, imposing higher demands on energy planning, dispatching, and control. Acrel's AcrelEMS smart energy management system for industrial parks, featuring predictive analytics, optimized dispatching, and scenario-adaptive solutions, provides a full-cycle digital solution from initial planning to post-construction operations. This system serves as a robust foundation for clean, low-carbon, safe, and efficient energy development in industrial parks.

 

 

1. Scientific Planning: Let New Energy Investment Have a Basis and Say Goodbye to Blind Decision

 

  For all construction teams, the core challenges in park development include determining optimal PV capacity, selecting appropriate energy storage systems, planning charging station layouts, and estimating ROI timelines. Relying solely on experience often leads to wasted capacity and underperformance. Acrel's microgrid capacity planning tool, however, provides data-driven solutions by integrating local electricity pricing policies, wind/solar resources, and park-specific load profiles, ensuring every investment decision is data-driven and well-informed.

 

 This comprehensive toolkit covers three core planning modules: photovoltaic systems, energy storage, and charging infrastructure, featuring multi-strategy simulation analysis for precise capacity estimation and one-click solution generation. The PV capacity planning module automatically recommends installation volumes based on solar radiation data and historical electricity consumption patterns, while evaluating self-consumption ratios and generation revenue. The charging infrastructure planning module supports customizable AC/DC charging station ratios, provides physical layout previews, and enables rapid configuration plan generation with capacity requirements.

 

  The tool simultaneously visualizes load curves, PV output, and pricing strategies, supporting multiple operational approaches including anti-ride-back control, renewable energy integration, peak-valley arbitrage, and demand management. Designed for diverse industrial park scenarios, it eliminates speculative planning in the early stages while clearly demonstrating ROI and environmental benefits.

2. Full Dimension Control:AcrelEMS Intelligent Platform,Create the Energy Brain of the Park

 

 If planning tools serve as the 'compass' for energy infrastructure development in industrial parks, then the AcrelEMS smart energy management system for microgrids functions as the 'intelligent brain' for energy operations. With its core model of 'predictive planning, optimized scheduling, and scenario adaptation,' the system provides a digital platform solution for energy planning, operation and maintenance, and optimized scheduling in industrial parks, while also acting as a critical link between energy production and consumption.

 

The platform delivers full functionality with visible cost reduction and efficiency gains

 

Acrel EMS integrates comprehensive modules including power generation monitoring, electricity consumption analysis, charging station management, and carbon emission statistics. It provides real-time displays of key data such as park power generation capacity, electricity load, daily power output, and comprehensive electricity costs, enabling full control over energy status. Through platform management, the park's renewable energy absorption rate has significantly improved.

 

The platform also quantifies the park's carbon reduction achievements, clearly displaying key metrics such as carbon emission reductions, standard coal savings, equivalent tree plantings, and equivalent green certificate allocations. This provides precise data support for carbon asset management and green power/certification trading, helping the park steadily advance toward its zero-carbon goals.

 

2.1 Optical Power Prediction

 

Photovoltaic power generation depends on solar irradiance and is highly susceptible to factors such as cloud cover, weather, and seasonal variations, resulting in highly random and intermittent output. This forecasting technology can predict the actual photovoltaic output power for different time periods (short-term/ultra-short-term) in advance, addressing the challenge of "unpredictable output" and preventing dispatch imbalances, solar curtailment, or power supply shortages caused by output fluctuations.

 

 

2.2 Load Forecasting

 

The power load in industrial parks is influenced by production planning, manufacturing processes, consumption patterns, seasonal climate, and policy adjustments (such as peak-shaving measures), exhibiting significant fluctuations between peak and off-peak periods. Load forecasting enables early prediction of demand patterns across different timeframes, effectively addressing supply shortages or surpluses caused by unpredictable load variations. This provides accurate demand-side data to support coordinated multi-energy dispatching.

 

 

2.3 Economic Optimization of Microgrid Dispatch

 

Based on the numerical weather prediction, photovoltaic power generation prediction (wind power generation prediction) and load prediction, the dynamic operation strategy of the wind-solar-storage load microgrid is provided by using the optimization algorithm (linear solver, group intelligent algorithm and reinforcement learning model), and the output of the adjustable equipment is the operation power curve.

 

 

 

 

3. Hardware and software integration ensures stability and reliability

 

The Acrel EMS Industrial Park Microgrid Smart Energy Management System provides a digital platform solution for energy planning, operation and maintenance, and optimized dispatching. This system not only serves as a technical solution for distributed energy integration and energy efficiency improvement, but also acts as a critical link between energy production and consumption. Through its core model of "predictive control, optimized dispatching, and scenario adaptation", it meets the needs of different users for cost reduction and supply assurance while providing flexible regulation resources for the power grid. In the process of promoting clean and low-carbon energy transition and building a new power system, it holds irreplaceable core value and broad development prospects.

 

 

Beyond its smart energy management system for microgrids, Acrel provides complementary hardware solutions—including microgrid protection devices, measurement and control systems, energy meters, gateways, and coordination controllers—to deliver a comprehensive one-stop solution for energy management in industrial park microgrids.
