Industry Challenges: Grid Vulnerabilities in the Renewable Energy Surge

The rapid integration of photovoltaic (PV) systems, wind farms, and electric vehicle (EV) charging infrastructure has exposed distribution grids to three critical risks:
🔺 Severe Voltage Fluctuations – Threatening power stability for sensitive facilities (e.g., hospitals, semiconductor plants).
🔺 Three-Phase Unbalance – Caused by uncoordinated distributed generation and uneven load distribution.
🔺 Widening Peak-Valley Demand Gap – Under-supply during peak hours, reverse reactive power flow during valleys, and soaring carbon emissions.
Traditional voltage regulation devices—plagued by short lifespans, slow response, and poor adaptability—struggle to address these challenges. What is the solution?
