“小改造”派上大用场 山东德州试点应用“一发双收”逆变器

Core Viewpoint - The rapid growth of distributed photovoltaic (PV) installations is increasing the difficulty and pressure on grid regulation, necessitating the urgent development of the "four capabilities" (observable, measurable, adjustable, controllable) in distributed PV systems [1] Group 1: Distributed PV Challenges and Solutions - Shandong Province is a major area for distributed PV installations, which are often scattered and include many rural household systems, leading to challenges in real-time data transmission and grid management [1] - The State Grid Dezhou Power Supply Company is piloting the "one generation, dual collection" inverter technology to enhance the "four capabilities" of distributed PV projects, addressing the difficulties faced in monitoring and control [1][2] Group 2: Technical Advancements - The "one generation, dual collection" inverter improves data collection and control response times, allowing for real-time monitoring and flexible regulation of distributed PV output [2] - This inverter technology features low latency, high reliability, and high precision, significantly enhancing the operational capabilities of distributed PV systems [2] Group 3: User Benefits and Implementation - Users can monitor their generation revenue through a mobile app, facilitating flexible adjustments to maximize earnings as renewable energy increasingly participates in the electricity market [2] - The modification cost for existing systems to implement the "one generation, dual collection" technology is minimal, requiring only a simple upgrade of the communication components [2] Group 4: Future Plans and Broader Application - Starting January 2026, the State Grid of Shandong plans to promote the "one generation, dual collection" technology across all new household distributed PV installations in the province, based on successful pilot experiences [3]
