Four trends are accelerating the construction of new systems

5SHY4045L0004 The Schneider Electric Institute of Business Value proposed that the four major trends of “clean and low-carbon, safe and flexible, digital, and market-oriented” will continue to affect all aspects of the entire power system, accelerate the construction of a new power system, and support the achievement of the “double carbon” goal.

Clean and low-carbon, with new energy as the main body is the core. With the continuous advancement of the dual-carbon process, the installed capacity of new energy and power generation will gradually increase, and the degree of electricity cleanliness in China will also be greatly improved. The power generation cost and development layout of new energy will become the key factors affecting its development. With technological progress and large-scale development, the levelized kilowatt-hour cost (LCOE) of new energy power generation represented by photovoltaic and wind power is declining year by year. In the future, China will also build a centralized and distributed renewable energy development pattern through the construction of multi-energy complementary large bases, trans-regional UHV transmission and distributed new energy construction, and promote the development of new energy.

5SHY4045L0004 Safe and flexible, the basis for large-scale application of new energy. In the process of low-carbon transition to replace fossil energy with new energy, the volatility and intermittency of new energy generation require that the power system must have flexibility. By expanding and adjusting the scale of power supply, coal and gas power plants are flexibly reformed; Increase energy storage capacity, including pumped storage and new types of energy storage; Tapping the demand-side potential, such as demand-side response and virtual power plant technology, will jointly become the basis for building the flexibility and stability of the grid system, and ensure the large-scale application of new energy.

5SHY4045L0004 Digitalization infuses the soul of the new power system. The new power system needs a lot of information collection and operation analysis to ensure the safety, stability and reliable power supply of the grid. Artificial intelligence, cloud computing, 5G and other digital technologies will achieve a full range of applications in all aspects of power generation, transmission, transformation, distribution, use, storage, etc., so as to promote the digital transformation of power systems. The development of digital technology, the formation of production factors with data as the core, and the deep integration of energy flow and information flow will inject soul into the operation of the new power system.

Marketization, auxiliary power system operation of the new power. In the process of power supply and demand balance of the new power system, the price policy and mechanism will become the basis of market allocation of resources, and the reform and improvement of the existing price mechanism and policy will effectively mobilize the enthusiasm of all links and enhance the flexibility of the system. Promoting the integrated and coordinated development of “source, network, load and storage” with new energy as the main body is an important driving force for building a new power system.

5SHY4045L0004 Digitization reshapes the demand-side ecology

As an important part of the power system, the demand side involves a wider range, and under the guidance of the long-term “baton” of carbon reduction, power users in various industries of society will also participate in this change. By reshaping the new demand-side structure of integrated source and network load and storage, integrated production and consumption, and comprehensive utilization of energy, we can help build a new power system and achieve the ultimate goal of safety, green, and economy.

5SHY4045L0004 This year, the National Development and Reform Commission and the National Energy Administration issued the Opinions on Improving the Institutional Mechanisms and Policy Measures for the Green and low-carbon Energy Transition, which has clearly proposed to promote the integration of demand-side adjustable resources into the power balance, play the role of demand-side resources to cut peaks and fill valleys, promote the balance of power supply and demand and adapt to the operation of new energy power.

As the new portrait of the future electricity demand side described by the Schneider Electric Institute for Business Value shows: in a carbon-neutral society in 2060, the demand side of the new power system will be a micro-power ecosystem with multiple forms of distributed energy, energy storage infrastructure, flexible intelligent distribution networks and considerable controllable loads.
