1、 Policy background

（1） Basis for integrated construction of wind solar energy storage and charging

The People's Government of Yinchuan City, Ningxia has released the "Yinchuan Electric Vehicle Charging Infrastructure Development Plan (2025-2030)". Among them, it is proposed to form an integrated energy network of "wind solar energy storage and charging". Build an energy network centered on charging stations, with wind solar energy storage and charging complementing each other, to achieve full regional coverage, improve charging efficiency, and ensure the supply of green energy

（2） Encourage investment in the construction of charging and swapping infrastructure in towns and villages where existing centralized wind farms, photovoltaic power stations, energy storage power stations, etc. are located

Integrate the construction of rural charging and swapping infrastructure in distributed photovoltaic and decentralized wind power projects, promote on-site consumption of green electricity, and achieve "green piles" where green electricity is available

（3） Key technologies to promote the energy revolution, achieve the 'dual carbon' goal, and build a new type of power system

2、 User demand

1. The user has many photovoltaic, energy storage, and distribution projects locally, but lacks experience in building comprehensive platforms and existing modules for integration

2. There are various types of equipment and communication protocols used in existing projects, as well as multiple subsystem brands;

3. The overall operation and maintenance cost is high, with multiple subsystems and multiple personnel responsible, and data sharing and interoperability between different systems is not possible;

4. The customer is transitioning towards a comprehensive energy solution, but lacks a holistic solution.

3、 Local project cooperation

1. County Cai Political Bureau EMS Project

Project situation: Adopting AcremEMS smart energy platform, integrating photovoltaic, energy storage, and charging piles to achieve multi energy complementarity, automatic control, helping users absorb photovoltaic power generation, conduct peak valley arbitrage, and reduce charging costs.

2. Photovoltaic (zero carbon rural) project for residents in a certain village

Project situation: Construction of rooftop photovoltaics for rural houses in the entire village, mainly for heating equipment functions. The project is equipped with 10kWh household energy storage cabinets to maintain the daily electricity needs of farmers. The AcrelEMS smart energy platform is connected to integrated light storage machines and over 60 heating devices, achieving overall strategic control of light, storage, and load.

3. Dairy Industry Technology Incubation Industry Center

Project situation: A newly put into operation industrial park, with self built photovoltaic, energy storage, and charging pile equipment. The operation data of the distribution room, photovoltaic, energy storage, and charging piles are synchronously uploaded to the EMS3.0 cloud platform to achieve operation monitoring and strategic control of the station, help users consume photovoltaic power generation, and reduce charging costs.

4、 Partial extension of dual carbon policy

Carbon verification support: Support the tracking and tracing of process data and original vouchers for carbon emission accounting, achieve online automatic generation of carbon emission reports, and complete the collection and export of carbon verification related materials.

Energy consumption and carbon emission budget management: Analyze and predict the energy consumption and carbon emissions of industrial enterprises and parks within a time period, and achieve full process management and dynamic adjustment of energy consumption and carbon emissions.
