A new white paper, ‘Enhancing System Stability through Grid-Forming Energy Storage Technologies,’ has been launched by Energy-Storage.news, sponsor Kehua Digital Energy and technical partner TÜV Rheinland.
The paper was launched yesterday (23 June) at Intersolar Europe 2026 in Munich, Germany, and Energy-Storage.news readers can access it for download via this link, or from the Resources page of the website.
Produced in context of the rapid transformation that global power systems are undergoing and grid-forming (GFM) technologies will play a crucial role in enabling the integration of renewable energy and retirement of fossil fuel-based synchronous generation.
The white paper identifies three major challenges facing European power systems: declining inertia, operation of weak-grid nodes and a limited capability to black start idle power infrastructure.

GFM technology can solve these issues by providing voltage and frequency support, enhancing system stability and enabling increasing shares of variable renewable energy (VRE) generation.
The paper also introduces sponsor Kehua Digital Energy’s grid-forming power electronics and energy storage system solution.
TÜV Rheinland has conducted a comprehensive technical assessment of Kehua’s grid-forming architecture, control strategy and performance.
“Grid-forming energy storage is becoming essential for future high-renewable power systems,” Mario Comboni, Global Head of Technology Center of Power Electronics Products Services, TÜV Rheinland Group, said.
“Independent validation strengthens technical credibility for global stakeholders.”

The white paper is also available from Kehua’s website. It will be updated accordingly as technology and industry applications evolve.
“Grid-forming is a proven concept in enabling system stability amid high penetration of renewable energy on islands and remote regions around the world for around two decades. More recently, it has become apparent that grid-forming technology will be essential to achieve the same goals in grid-connected regions everywhere,” Energy-Storage.news editor Andy Colthorpe said.
“Individual countries and transmission service territories in Australia, the US, Germany and the UK are among those already moving forward with adoption, while Europe’s association of transmission system operators, ENTSO-E, is developing technical standards for the widespread implementation of grid-forming capabilities across its networks.
“Yet industry-focused resources that further the understanding of the sometimes-complex applications and system modelling required are still relatively scarce. That is why Energy-Storage.news is very proud to have partnered with Kehua Digital Energy and TUV Rheinland to provide this sponsored white paper for our readers.”
