- Smart energy system with nuclear energy and renewable energy -

With the decrease of the proportion of coal power installed and the increase of the proportion of renewable energy generation, nuclear power will play an important role in the long-term safe and stable operation of the power grid. Nuclear energy relies on its stable and reliable operation, long refuelling cycle and other characteristics, as a clean baseload energy can solve the problem of large-scale power supply security and stability, nuclear energy and wind, light and other renewable energy synergistic and complementary development of the situation needs to be formed.

Therefore, starting from the actual situation of China's energy endowment and adapting to the needs of energy transformation, the collaborative intelligent system of nuclear energy and renewable energy takes into account the strategy, necessity, feasibility and economy, and can effectively reduce the abandonment of wind and light, achieve efficient allocation of resources, optimize China's energy structure, break through the constraints of fossil energy, and achieve emission reduction targets under the premise of ensuring energy security. It is an important way for China to achieve the development of clean and low-carbon energy and energy transformation under China's "30·60 goal", which has great value for China to achieve ecological civilization construction and lead global climate governance, and is an important choice to ensure the coordinated development of energy supply, economic development and ecological environment.

Nuclear energy and renewable energy collaborative intelligent system is a smart energy system with power system as the core, smart grid as the basis, nuclear energy and renewable energy as the main body, with an appropriate amount of hydropower and thermal power, to achieve cold, hot, gas, water, electricity and other energy complementary, improve energy efficiency.

The nuclear and renewable energy collaborative intelligent system architecture consists of four main parts: development of the infrastructure system, including nuclear and renewable energy infrastructure; Technical support system, including distributed energy technology, smart grid technology, big data technology, Internet of Things technology and multi-energy complementary technology; Consumption systems, including energy trading, energy services, decision support and optimization control; Standard system, including demand response, energy coordination, energy storage, energy prices, energy trading, network security and a series of standards.

By deeply integrating modern information technology, intelligent control and optimization technology with modern energy supply, storage and transportation, and consumption technology, the system provides a more scientific forecasting, decision-making and interactive platform for energy optimization management and multi-function collaboration, and creates a new way for consumers to obtain energy, store energy and even sell energy. We will promote the increase in the proportion of nuclear energy and renewable energy and the adjustment and optimization of the energy structure, promote the transformation of users' energy use concepts and the improvement of terminal energy efficiency, and achieve energy security, clean, economical and sustainable development under the constraints of energy conservation and emission reduction targets.

In this system, the comprehensive utilization of nuclear energy can provide a variety of secondary energy. For example, in the case that the scenery can not provide effective power supply, nuclear energy exerts the baseload energy characteristics to provide power supply guarantee; In the case that wind provides an effective power supply, nuclear energy through comprehensive utilization, the energy is converted into hydrogen, fresh water, molten salt heat storage and other ways of storage and transportation, improve the overall economy and utilization rate of the system.

Nuclear energy and renewable energy collaborative intelligent system adopts advanced nuclear energy and renewable energy supply and energy conversion technology, energy transmission technology, energy consumption technology, intelligent processing technology, comprehensive system optimization technology, to achieve independent, safe, clean, diversified and efficient energy supply and consumption. The main features of the system include safety, cleanliness, diversity and economy.

Safety: The total amount of energy in the collaborative intelligent system of nuclear energy and renewable energy is stable and abundant, and the sustainability is strong, and the energy supply in the system is low in external dependence.

Clean: The energy supply in the collaborative intelligent system of nuclear energy and renewable energy is low-carbon energy and environmentally friendly.

Diversity: The continuity of energy supply in the collaborative intelligent system of nuclear energy and renewable energy is strong. As the base load, nuclear energy supplements each other through cold, hot, gas, water, electricity and other energy sources, and is applied flexibly to ensure a variety of energy supplies.
