Past Activities

Work at GO15 was organized within several types of Joint Activities, which include working groups, joint projects and workshops. In 2014, Joint Activities were organized within 10 working groups, each led by one of the GO15 members.

WG #1: Synchrophasor Applications

Leader: ONS (Brazil) Synchrophasor technology,  also known as Phasor Measurement Units, has been identified as having great potential to improve reliability of power grids and improve their efficiency. It can help deliver better real-time tools that enhance Power Grid Operators’ situational awareness and provide synchronized high-resolution measurements of system dynamic behavior leading to improved system […]

WG #2: Enhanced Security

Leader: Terna (Italy) Due to the current concerns about power system vulnerability, WG #2 is focusing on the criteria, best practices and procedures to enhance the power system resilience. Using this benchmark, the WG members will have an opportunity to check and improve their internal procedures and organization. In 2013, the WG #2 will have […]

WG #3: Integration of Renewables

Leader: National Grid (UK) The integration of renewables into power grids form an important initiative in ensuring that the objectives of GO15 are met. The working group was formed in early 2009 with the view of collaborating with utilities from around the world. In 2013, the WG #3 will cover 7 areas of investigation and will include 2 […]


Leader: REE (Spain) In a smart world, electric systems will be much more developed in terms of efficiency, variable load and intermittent embedded generation. The load will be price and frequency sensitive. Along with intermittent embedded generation, which will net the load, and active load management will be needed. In order to operate networks and […]

WG #5: HVDC Application

Leader: ONS (Brazil) Integration of HVDC links within synchronous power systems is on the rise and many new links are being planned worldwide for commissioning over the coming years. In such connections, the degree of interaction between the HVDC links and their methods of control and operation presents significant new challenges as they differ from […]

WG #6: Electric Vehicles

Leader: PJM Interconnection (USA) While the deployment projections of PEVs indicate slow and progressive development over the next 5 to 15 years, PEVs will have high probability of success and significant impact on electric systems. Plug-in vehicles are being developed by many of the global automobile manufacturers: General Motors, Mitsubishi and Nissan have launched the […]

WG #7: Common Modeling

Leader: MISO (USA) Storage technology not only enables converting intermittent renewable generation into firm dispatchable generation, but  it also provides potential for shifting load, reduce congestion, and frequency and VAR support. It can be used as a mechanism to increase system security and optimize the performance of the transmission network. Challenge Renewable and low carbon power, demand response, […]

WG #8: Finance and Regulation

Leader: RTE (France) Economic scenarios for the future confirm the growing weight of electricity and, as a consequence the central role of Power Grid Operators as an interface between generation and demand by guaranteeing the security of supply. The following challenges have been identified: – Electricity is not yet at the disposal of all populations […]

WG #9: Control System Architecture Standards

Leader: SGCC (China) The “smart grid” is becoming more and more popular in the world and is covering all the sectors of the power industry including generation, transmission, distribution and consumption. The “smart grid” will involve smart control centers, smart substations, smart power plants as well as smart consumers. Challenge In order to operate the […]


Leader: Elia Group (Belgium) Each year natural disasters and complex emergencies affect millions of people around the world. Recent tragedies, such as the earthquake in Japan in March of 2011, make us even more aware of the impact of such events. During these natural or man-caused disasters electricity grids are often seriously damaged or even […]
