Unlocking the future of power systems with IEC 61850: How global standards shape energy transformation.

The energy sector is undergoing an unprecedented transformation. IEA’s World Energy Outlook projects that global electricity demand will double by 2050. As global demand increases and sustainability is prioritised, the traditional unidirectional power grids are transforming into dynamic, multidirectional systems. This evolution is largely driven by the adoption of advanced interoperability standards like IEC 61850, which ensures seamless integration and management of modern power systems.

From centralised to decentralised grids: A new paradigm

According to the IEA, global renewable electricity generation will exceed 17,000 TWh (60 EJ) by 2030, representing an almost 90% increase from 2023. Distributed Energy Resources (DERs), such as solar panels, wind farms, and energy storage systems, are changing how we generate and distribute electricity. Traditional power grids, originally built for one-way power from central stations, now must handle two-way energy flows, constant monitoring, and fluctuating loads.

For energy engineers and system integrators, this shift emphasises the need for flexible and scalable solutions to address the complexities of modern grids. Digitalisation is crucial in managing decentralised energy systems and enabling efficient demand-supply communication. IEC 61850 addresses these challenges by providing a universal standard that ensures reliable communication and interoperability across energy devices, while supporting the efficient deployment of communication systems for a broad range of energy applications, from substations to microgrids.

Why IEC 61850 is the backbone of modern power systems

Initially developed for substation automation, IEC 61850 has become a cornerstone for the broader energy ecosystem. Its standardised communication protocols—such as MMS, GOOSE, and Sampled Measured Values (SMV)—facilitate seamless data exchange, ensuring system-wide consistency and reliability and deployment efficiency. The framework enables:

• Interoperability: Simplifies integration across devices from multiple vendors, reducing system complexity.
• Consistent Data Models: Supports real-time operations and enhances DER integration.
• Future-ready Systems: Scales to accommodate multidirectional energy flows and evolving grid demands.

Enhancing energy systems through data and communication solutions

IEC 61850 communication addresses critical challenges in energy systems by supporting applications such as:

• Distributed Energy Resource Management Systems (DERMS): Real-time monitoring and coordination of DERs to stabilise and optimise grid operations.
• Energy Storage Integration: Efficiently managing grid-scale battery systems (grid-scale BESS) to balance supply and demand in renewable-heavy grids.
• Substation Automation: Enabling real-time communication and reliability enhancements, crucial for modernising grid infrastructure.

Overcoming challenges with ruggedised solutions

Modern power systems need robust solutions to ensure reliability because they operate in demanding environments. The consistent performance of IEC 61850-based systems is enabled by resilient designs and advanced communication. These solutions empower energy operators and integrators to build scalable, future-ready systems that adapt to diverse conditions.
