Wind power generation “depends on the sky to eat”, with strong randomness, volatility and intermittency. Energy storage, as a flexible control tool, can effectively deal with this challenge, and is the basic element of the new power system “source network load and storage”. Although the realization of energy storage is currently in the stage of coexistence of multiple technical routes, ABB has mature solutions in the field of physical energy storage and electrochemical energy storage based on its deep industry expertise, supporting energy manufacturers, manufacturers and operators in the industrial chain for commercial deployment.

At present, physical pumped storage is still the main energy storage technology in China, and pumped storage is also the energy storage technology with the largest installed capacity. ABB can provide technologically advanced electrical application solutions for the construction of pumped storage hydropower stations, such as in the low-voltage system of hydropower plants. ABB iVD4 medium voltage switching solutions, Emax 2 air circuit breakers, and Tmax XT MCCB protect circuits and electrical equipment from temperature rise, overload, short circuit and ground faults.

Equipped with ABB Ability smart energy management platform, ABB eStorage smart energy storage hut can realize second-level flexible charge and discharge regulation of energy storage, smooth the volatility of new energy generation on the distributed generation side, reduce the impact on the power grid, improve the local consumption rate of new energy, and support the construction of grid-type energy storage demonstration projects.

In addition, cable accessories are a key link in the connection of cable systems and electrical equipment, and the high quality, easy operation, high interchangeability and versatility of cable accessories are the basis for the construction and installation of the entire electrical system. The new ABB SoliMold series 110kV cable accessories displayed on site are mainly used in the field of high-voltage AC power transmission. The connection of high-voltage power cables with electrical equipment or overhead lines can meet the working requirements of new energy power systems in harsh environments.

Green power distribution

The power grid is the “link” and “bridge” of the new power system. Based on the three major initiatives of supporting high-flexibility distribution networks, creating high-toughness distribution networks, and green and safe distribution products, ABB power grid industry solutions run through the user side, distribution network side, and the efficient operation of the grid, promoting the sustainable operation of the distribution network, and helping to build a new power system.

PFVI401

ABB Ability edge side energy optimization system connects power grid, photovoltaic, energy storage, charging pile, distribution system, building automation system, meteorological system, production management system, through digital means to coordinate the “source network load and storage” precise regulation, improve the local consumption of new energy

Promote the flexible adjustment and response ability of the user side, and improve the active support ability of new energy; Integrate decentralized response resources and connect to the virtual power plant dispatching platform to support the balance of power supply and demand without affecting production and life as much as possible.

ABB’s observable, controllable, adjustable, and measurable multistage active distribution defense solution can consolidate the power supply guarantee capability. ABB’s new generation of medium pressure gas cabinets, with green properties, help urban power distribution to achieve full scene environmental protection. The Safe Air 10kV ring cabinet and Prime Gear ZX0 10kV primary gas cabinet displayed on site both use dry air as an insulating medium to replace the powerful greenhouse gas sulfur hexafluoride (SF6) and promote greenhouse gas emission reduction in the power industry with innovative technology.

Green electricity

Driven by both the energy revolution and the digital revolution, electrification has expanded beyond the traditional boundaries of the power sector. ABB Ability EAM energy and asset management solutions can monitor users’ energy use status in real time, and identify potential energy saving points based on horizontal (energy use of the same equipment) and vertical (historical energy use of the same equipment) comparison, helping users save energy and reduce energy costs. In addition, with the more and more widely used semiconductor devices, the problem of power quality in electrical systems is becoming more and more prominent. ABB Smart PQS integrated power quality management solution can provide functions such as bidirectional reactive power compensation, three-phase unbalance and harmonic control according to customer needs, so as to achieve the comprehensive power management goal of the system. According to the characteristics and needs of different industries, ABB closely follows the development of new business forms and models, provides perfect solutions, and promotes the low-carbon and digital transformation development of industrial, data center, transportation, construction and other industries.

In addition, in the new power system, the load side resources such as adjustable loads, electric vehicles, and energy storage are no longer simple “consumers” of electric energy, but also “producers” of electric energy. For example, in ABB Beijing, Xinhui manufacturing base and ABB Xiamen Industrial Center, the factory uses the roof to build photovoltaic power generation, and the surplus power is sent back to the grid; ABB’s extensive vehicle-to-grid (V2G) technology for electric mobility enables electric vehicles to charge during off-peak hours and discharge to the grid during peak hours. The Photovoltaic Building Integration (BIPV) model, in which ABB is actively involved, applies DC distribution, and in the case of grid-connected to the grid, the electricity generated by the building can be directly fed back into the grid.

When electrical equipment and systems are put into operation, how to ensure safe, reliable, efficient operation, digital empowerment, and low carbon environmental protection is crucial. ABB focuses on the value evolution during the whole life cycle of electrical equipment, focusing on the five stages of “running-in period, stable period, attention period, retirement period and life extension period”, and launches PowerCare worry-free service and OneFit® alternative service to provide users with green services and solutions throughout the whole life cycle of electrical equipment. To help users in various industries achieve safe, smart and sustainable electrification operations.
