Enhanced Grid Reliability and Resilience through Advanced Monitoring and Control is Driving Demand 

The use of digital substations is increasing as they significantly improve grid resilience and dependability. Real-time monitoring of critical equipment characteristics, advanced fault detection, and automated restoration features are made possible to accomplish this resilience and dependability. Utilities are able to promptly address and fix possible issues before they create major disruptions due to this thorough control.

In order to meet the increased demand for modernization and to improve grid stability through sophisticated monitoring and control, governments and businesses across the world are working together to develop digital substations. For example, in April 2020, ABB installed the first 500 kV digital substation in South America at the São Goncalo solar photovoltaic (PV) project owned by Enel Green Power in Piaui, Brazil. In addition to being the first digital substation of its sort to operate at this voltage globally, this represents a major advancement in the delivery of emission-free electricity from the biggest solar PV plant in South America to Brazil's 500 kilovolt (kV) transmission network.

Integration of Renewable Energy Sources and Distributed Generation Propelling Market Growth

Traditional substations lack the potential to manage the fluctuating and two-way power flows inherent in these sources. With advanced monitoring, control, and communication systems, digital substations offer the flexibility and resilience needed to handle the intricacies of a grid that is becoming more and more reliant on renewable energy. By optimizing power flow, enhancing grid stability, and quickly addressing fluctuations brought on by intermittent renewable generation, these cutting-edge substations help operators sustain a decentralized energy infrastructure and enable a smooth transition to a cleaner energy in the future.

In January 2022, Hitachi Energy secured a dependable power supply in East Java, Indonesia, by installing a 150kV digital substation at PT PerU.S.haan Listrik Negara. Connecting the expansive 200-hectare Sidoarjo Industrial Estate to PLN's power grid, this 1.5-hectare substation, the first and largest digital substation in East Java, ensures steady electricity for the estate's several significant manufacturing enterprises. The design of the substation will also make it easier to integrate renewable energy sources, which will further enable decarbonization and have a good effect on the East Java Province's economic growth, according to Hitachi.
