DEWA patents smart simulator to strengthen Dubai’s power grid

Dubai Electricity and Water Authority (DEWA) has secured a UAE patent for an advanced simulator designed to test substation automation systems, marking a significant step in strengthening grid reliability while reducing operational risk and cost.

The Feeder Input-Output Simulator for Substation Automation Applications has been developed in-house and is now in active use within DEWA’s Power Transmission Division. The innovation allows engineers to safely and accurately test complex automation systems in a controlled virtual environment, without the need to work on live electrical equipment or shut down substations.

The simulator replicates the behaviour of real electrical assets such as switches and protection relays, transmitting virtual signals to actual control systems. This enables engineers to assess multiple operating scenarios, verify system responses and identify potential issues before systems are deployed in the field.

Saeed Mohammed Al Tayer, Managing Director and Chief Executive Officer of DEWA, said: “This technology reflects the wise leadership’s vision to promote innovation that shapes a more prosperous and sustainable future for our nation. It embodies DEWA’s approach to turning applied innovation into tangible solutions that strengthen the resilience and sustainability of our energy infrastructure.

“The simulator underscores the ingenuity of our Emirati staff in developing advanced tools that enable the safe and efficient testing of substation automation systems while accelerating project completion, reducing costs and enhancing safety standards.”

Simulator minimises risks, boosts efficiency

By removing the need to test systems using live current, the simulator significantly lowers safety risks for engineers while ensuring that automation systems are fully validated before they go live. DEWA said the tool has already delivered measurable benefits, including faster testing cycles, reduced operational costs and improved overall system readiness.

The innovation also supports DEWA’s wider push towards digital and smart transformation in the energy sector, helping to modernise grid operations and align them with international best practice.

Hussain Lootah, Executive Vice President of Transmission Power at DEWA, said: “This device is a significant addition to the tools used by the Power Transmission Division, as it provides a safe and effective environment for testing substation automation systems. It enhances the efficiency of work teams and accelerates task completion without compromising network safety.”

DEWA said the simulator reflects its long-term commitment to organisational innovation and employee-led technical solutions that deliver practical impact. By investing in advanced engineering tools, the authority aims to ensure the reliability, safety and sustainability of Dubai’s electricity network as demand grows.

The patented system reinforces DEWA’s position as a regional leader in energy innovation and supports the delivery of resilient infrastructure that meets the needs of the city, its economy and its communities.
