With the increase in distributed generation and the growing risk of excess energy in the National Interconnected System (SIN), the ONS (National System Operator) sent to ANEEL, last Friday (31), a new Emergency Plan.
The proposal seeks to establish clear measures to manage critical situations when conventional generation control alternatives are no longer viable.
The plan includes the management of Type III power plants, small-scale plants connected to the distribution network. These resources mainly include small hydroelectric plants (PCHs), which ultimately can be used to control the flow of energy and ensure the stability of the national electricity system.
By resorting to decentralized sources, the ONS (National System Operator) seeks to avoid serious problems such as network overload and cascading outages, which could directly affect the energy supply to the population.
Although the ONS (National System Operator) does not have direct control over these units, the plan establishes that, in critical moments, it will be possible to temporarily reduce generation from these sources in order to control the system frequency and guarantee operational security. without.
Christiano Vieira, Director of Operations at ONS, explained that the plan aims, above all, to maintain the stability of the electrical system, especially in a context of expansion of the... GD (Distributed Generation).
“This exceptional measure preserves the balance between load and generation and guarantees the stability of the National Interconnected System (SIN). In the current scenario of distributed generation expansion, this precaution is fundamental to ensure the continuity of energy supply and avoid risks to the system's operation,” stated the director.
