The era of "four possibilities" for distributed photovoltaics has arrived!ACCU-100MIntelligent controllers light up a new era of green energy

Introduction: Green Revolution in the Era of Distributed Photovoltaic "Four Feasible"

Driven by the energy transition and the "dual carbon" goal, distributed photovoltaics are moving from "wild growth" to a new stage of "high-quality grid connection". However, the shortcomings of traditional photovoltaic systems, such as being unobservable, unmeasurable, unadjustable, and uncontrollable, have led to a decrease in grid stability, an increase in curtailment rates, and limited user benefits. To solve this problem, the National Bureau of Energy has clearly put forward the requirements for the "four possibilities" technology of distributed photovoltaics, promoting the industry to upgrade towards intelligence and controllability. In this context, the Ankerui ACCU-100M intelligent controller has emerged, with "full sensing, precise regulation, safety and reliability, cloud edge collaboration" as its core capabilities, injecting new momentum into the large-scale and efficient development of distributed photovoltaics, and opening up the "smart era" of green energy.

1 Technical background: The inevitability of the "four possibilities" of distributed photovoltaics

With the installed capacity of distributed photovoltaics exceeding 100 million kilowatts, the power grid's ability to absorb new energy is facing severe challenges. There are three major pain points in traditional photovoltaic systems:

①Blind tuning risk:The mismatch between photovoltaic power generation and grid load leads to voltage exceeding limits and power reversal;

②inefficiency:Lack of dynamic adjustment ability and high rate of abandoned light;

③Difficulties in operation and maintenance:Slow fault location, delayed response, and high maintenance costs.

To address these issues, the National Development and Reform Commission has issued the "Guidelines for Evaluating the Carrying Capacity of Distributed Power Sources Connected to the Power Grid", which explicitly requires distributed photovoltaics to have "observable, measurable, adjustable, and controllable" capabilities to achieve bidirectional interaction with the power grid. This policy orientation has given rise to the intelligent controller market represented by ACCU-100M.
