Speech Title & Abstract

Advancing the Construction of a New Type of Power System under the “Dual Carbon” Goal

The new power system is the core of the energy internet and serves as a pivotal platform for achieving the “dual carbon” goals. It undertakes two important tasks: first, to achieve its own secure, clean, low-carbon, and efficient transformation, becoming a zero-carbon power system; second, to promote deep decarbonization in energy-consuming sectors such as industry, construction, and transportation through the substitution of electric power, thereby assisting the entire society in achieving carbon neutrality goals. The construction of a new power system requires strengthening the development of four major systems: a complementary clean energy supply system, a modernized power grid system, an intelligent energy use system, and an institutional guarantee system.

Speech Title & Abstract

The New Energy Industry Needs New Technologies for Safe and Long-duration Energy Storage

Under the guidance of the “dual carbon” goal, new energy storage has become a crucial anchor for the development of the new energy industry. Energy storage systems can help mitigate energy fluctuations, achieve smooth energy output, and stabilize energy supply. They serve as an important means to address the current shortcomings of mainstream zero-carbon new energy technologies. Accelerating the large-scale application of new energy storage technologies has been included in the “14th Five-Year Plan” and is a long-term goal for 2035.

The energy storage industry imposes strict requirements on batteries in terms of safety, cost-effectiveness, and independent intellectual property rights. Zinc-bromine liquid flow batteries, with their characteristics of zero explosion risk, low cost, long lifespan, easy integration, and maintenance, are considered to be highly competitive for large-scale, long-duration energy storage applications. However, related technologies are still in the developmental stage internationally and face various technical challenges such as zinc dendrite formation, zinc passivation, and bromine shuttle. Additionally, in large-scale battery scenarios, the stack system also encounters issues such as high voltage drop, high efficiency loss, and poor mass transfer within the electrodes.

Addressing these challenges, the team led by Zhizhen Ye has developed five core technologies for zinc-bromine liquid flow batteries: precision-controlled energizing bipolar plate technology, ultrafine pore bromine-resistant membrane technology, solid bromine strong electrolyte activation technology, unique flow field pipeline stack design, and integrated sealing technology for preventing blockage and leakage. These advancements mark a solid step towards the industrialization of zinc-bromine liquid flow batteries.

Advanced Prediction Techniques Applied to Smart Grids With High Penetration of Renewables

In 2015, countries around the world reached the Paris Agreement and began reducing emissions as soon as possible to deal with the increasingly prominent issue of climate change and achieve the goal of carbon neutrality. Many countries, including China and the USA, have proposed national strategies to strengthen power grids to facilitate major government initiatives, such as increasing the penetration of renewable energy and electrifying transportation and other industrial and commercial sectors. At the same time, power system industry is shifting towards a new digital era to better manage risks in volatile energy commodities, increase customer engagement, and enhance efficiency through grid optimization. Data analytics plays a vital role in this transformation and, therefore, different measurement architectures have been used and implemented to facilitate the data capturing process and supervisory control at the generation, transmission, and distribution levels. Based on the massive measurement data, advanced prediction techniques driven by artificial intelligence will bring revolutionary changes to the power industry. This speech will briefly introduce advanced prediction techniques and review the recent results on some smart grid challenges addressed by novel prediction techniques.

Speech Title & Abstract

Triboelectric Nanogenerators for Energy and Self-powered Sensors

Triboelectric nanogenerator (TENG) was invented by us in 2012, which is based on coupling of triboelectrification and electrostatic induction effects for converting mechanical energy into electric power. TENG is playing a vitally important role in the distributed energy and self-powered systems, with applications in internet of things, environmental/infrastructural monitoring, medical science, environmental science, and security. In this talk, we first present the physics mechanism of triboelectrification for general materials. Our model is extended to liquid-solid contact electrification, reviving the classical understanding about the formation of electric double layers. Secondly, the fundamental theory of the TENGs is explored based on expanded Maxwell equations for a mechano-driven system. We will present the applications of the TENGs for harvesting all kind mechanical energy that is available but wasted in our daily life, such as human motion, walking, vibration, mechanical triggering, rotating tire, wind, flowing water and more. Then, we will illustrate the networks based on triboelectric TENGs for harvesting ocean water wave energy, for exploring its possibility as a sustainable large-scale blue energy for humankind. Lastly, we will show that TENGs as self-powered sensors for actively detecting the static and dynamic processes arising from mechanical agitation using the voltage and current output signals.
