ONS’s International Strategic Relationship

ONS continued, in 2015, its participation in GO 15 - Sustainable and Reliable Power Grids, for considering it an important forum and unique for the treatment of subjects relevant for the operation of the Brazilian electric power system. ONS participated in the studies developed considering its priority issues, and has coordinated directly, since 2014, some of these works:

• Evaluation of the impact and proposition of solutions to ensure electric power systems’ secure operation due to the significant penetration of new renewable energy sources, wind and solar, centralized and decentralized;
• Application of Phasor Measurement Units (PMU), especially in real time;
• Security and reliability, focusing on dynamic system assessment, preventive measures in the operation planning phase;
• Electric power systems’ability to face natural disasters;

These works will have their final results presented in 2016, although some relevant intermediate results have already been incorporated into ONS’s practices.

Considering the world’s supply and demand evolution concerning electric power, ONS also monitors issues that will have important repercussions to the BIPS’s operation, such as:

• Improvement of energy management systems used in real time;
• New IT solutions for electric power systemsoperation;
• Development and penetration of new renewable sources;
• New roles and relationship between Distribution and System Operators.
