Pillar 2 – System Operator Technical Support
Led by NREL, a holistic system operator technical assistance and capacity building program approach has been developed to ensure robust and impactful support to partner country system operators. Work programs are under development with developing country and emerging economy system operator partners in 10 countries that define priority activities for technical assistance and peer learning and exchange with the Founding System Operators and between all system operators.

G-PST Community of Practice for Southeast Asia’s Power System Operators: Learning from Vietnam’s Experience on High Fluctuations of Variable Renewable Energy in the Grid System
Based on the current power sector landscape in the ASEAN region, this community of practice event explores Vietnam’s system operator experience managing growing amounts of variable renewable energy generation on their power system. Since the unprecedented boom in solar energy development in recent years, Vietnam’s National Load Dispatch Center (NLDC) faced the challenge of stabilizing the power system in real time. To avoid straining the transmission and grid infrastructure, it is reported that around 365 million kWh of solar power was curtailed in 2020, and the plan was to increase the amount of electricity curtailment from solar generation to 1.3 billion kWh in 2021. Indonesia and Thailand, as two major countries in the region planning to install more than 5.8 GW of solar and wind energy combined by 2030, can learn from Vietnam’s experiences. Expert guests from Vietnam’s system operator, EVNNLDC, shares how their team handles the high fluctuations of solar and wind energy coming on to the grid and provides possible technical recommendations.
Featured Speakers:
- Karin Wadsack, NREL
- Warit Rattanachuen, HAPU
- Mr. Beni Suryadi (ACE)
- Mr. Dinh Xuan Duc (EVNNLDC)
- Mr. Elvanto Yanuar Ikhsan (PLN)

Power System Oscillation Source Analysis Using OSLp Tool
Power system oscillations are a phenomenon of periodic energy exchange across the system’s different components. Oscillations are inherent to each power system and can pose dynamic risks requiring the operator’s real-time situational awareness for potential stability issues. In partnership with India’s Power System Operation Corporation (POSOCO), the G-PST Consortium hosted a virtual peer-learning event highlighting POSOCO’s power system oscillation source analysis using oscillation source location software (OSLp) tool, developed by ISO New England Inc. The webinar:
- provides an overview of dissipation energy methods for oscillation source analysis,
- explores POSOCO’s experience with OSLp so far, and
- includes an interactive Q&A with expert presenters.
This event is part of the G-PST Consortium’s webinar series that spotlights partner country’s success stories, innovations, and insights to draw connections to universally relevant lessons for a global audience across a range of power system operations and variable renewable energy technology and integration topics.
Speakers include:
- Bin Wang – Assistant Professor, Department of Electrical and Computer Engineering, University of Texas at San Antonio
- Shri. Abishek R.S. – Deputy Manager (SRLDC), POSOCO
- MVD Raghava – Assistant Manager, POSOCO
- Mohit Joshi – Energy Systems Modeler and Analyst, National Renewable Energy Laboratory

G-PST Supports Indonesia’s System Operator Through Comprehensive Virtual Training Series
Under the G-PST’s System Operator Technical Support Pillar (Pillar 2), over 25 experts from across the G-PST core team and founding system operator network joined a virtual training series to present on power system management and VRE integration topics to staff at Indonesia’s power system operator, PLN. The series helps to broadcast to PLN staff the innovative and cutting-edge approaches that utilities around the world are using to integrate higher penetrations of VRE, and topics were chosen based on PLN’s highest priority needs and demands. The training series began in April 2021 and has completed nine installments.
View the recordings of each training:
- Industry and Researcher Perspectives on Control Center Upgrade Procurement
- The Readiness of SCADA/EMA in Control Centers for VRE Integration
- The Grid Code Adaptation Toward VRE Integration
- Smart Defense System Scheme to Maintain System Stability
- Cybersecurity Based on ISOC Concepts
- Advanced Forecasting of Short-term Load and Variable Generation
- Advanced Primary and Secondary Generation Control
- Advanced Dispatcher Training Simulator Toward VRE Integration
- Organizational Structure of the Control Center of the Future
Beyond this capacity-building series, the G-PST will continue to support PLN in modernizing its Sulawesi control rooms. Sulawesi forecasts a large uptick in near-term demand that will primarily be met with new renewables. The G-PST will aid PLN in determining how the control rooms might incorporate upgrades that better adapt to higher levels of VRE and modernize the functionality, database archiving, analytical capabilities, and the dashboard/ergonomics of the control room, among other areas that will be considered for improvement.
Power System Sharing Series #9 – Organizational Structure of the Control Center of the Future
The ninth installment of the Power System Sharing Series was focused on the organizational structure of advanced control centers. This webinar was delivered for PLN Indonesia staff and stakeholders. Speakers include experts from the Australian Energy Market Operator (AEMO) and California ISO. More information can be found on the Power System Sharing Series web page.
