Lin Weixing: Intrinsic safety at the electrical topology level is an important technical approach

Lin Weixing: Intrinsic safety at the electrical topology level is an important technical means that can effectively prevent battery modules from operating in overcharge or overdischarge states, thereby improving the safety of energy storage systems. In traditional energy storage integration, overcharge or overdischarge can cause serious damage to the battery, and even lead to safety hazards such as fire. Therefore, in order to ensure the safe and reliable operation of the energy storage system, measures must be taken to prevent the battery module from operating in an overcharge or overdischarge state.

Dialogue with Dr. Lin Weixing: How much application space does the power plant-level centralized access flexible energy storage system have?

Dialogue with Dr. Lin Weixing: How much application space does the power plant-level centralized access flexible energy storage system have?

Lin Weixing: The HarmoPower power plant-level centralized access flexible energy storage HLL-1500 and HLA-1500 series have single unit capacities of 3.354 MWh and 7.16 MWh, respectively. They are used to centrally locate energy storage devices in one or a few centralized locations, connecting to the 10kV or 35kV AC power grid via a combined inverter and step-up transformer to provide power reserves and regulation services. Following are some examples of scenarios suitable for 1500V centralized energy storage systems:

The era of large-scale energy storage has arrived! 300Ah+ energy storage battery cells are ushering in large-scale applications.

The era of large-scale energy storage has arrived! 300Ah+ energy storage battery cells are ushering in large-scale applications.

Recently, at RE+ the largest new energy exhibition in North America, RuiPu LanJun successfully won two energy storage orders for its Wendding 320Ah battery. They signed an 8.4GWh procurement agreement with POWIN, a leading US energy storage system integrator, and a 10GWh framework procurement agreement with SUNPIN SOLAR, a leading US photovoltaic power station system integrator and solar power plant developer. It is understood that RuiPu LanJun's Wendding 320Ah energy storage battery cells will be put into mass production in October.

Guangdong competes for the trillion-yuan energy storage market: focusing on output value instead of production capacity, launching the "strongest user-side energy storage policy"

Guangdong competes for the trillion-yuan energy storage market: focusing on output value instead of production capacity, launching the "strongest user-side energy storage policy"

Recently issued "Several Measures of Guangdong Province to Promote the Development of New Energy Storage Power Stations" (referred to as "Several Measures") proposes that new offshore wind power projects planned after 2022 and centralized photovoltaic power stations and onshore centralized wind power projects newly connected to the grid after July 1, 2023, shall be configured with new energy storage no less than 10% of the installed generating capacity for a duration of 1 hour. Subsequently, the configuration capacity of new energy storage will be adjusted according to the requirements of relevant power system safety and stability standards and the actual grid-connected scale of new energy. Existing new energy power generation projects are encouraged to configure new energy storage according to the above principles.

Three major trends in the development of new energy storage in Guangxi

Three major trends in the development of new energy storage in Guangxi

Recently, the first independent energy storage power plant peak regulation transaction was completed in the Guangxi power peak regulation auxiliary service market. This marks the market-oriented operation of energy storage auxiliary services, opening up a new business model for energy storage profitability. It further demonstrates the strategic value of energy storage as a grid-regulating resource, is conducive to the sustainable development of energy storage in Guangxi, and provides strong support for the construction of a new power system. Data from the Guangxi Power Grid Company of the Southern Power Grid shows that, as of August this year, Guangxi's new energy installed capacity reached 20.28 million kilowatts, accounting for nearly 30% of the region's total installed capacity, exceeding hydropower installed capacity and becoming the second largest power generation type in Guangxi. As an important technological means to enhance the power system's regulation capacity and expand the consumption space of new energy, new energy storage is transitioning from its initial stage to a fast-growing phase. The development of the new energy storage industry in Guangxi shows three major trends.
