In Part 1 of this series, we discussed some of the key grid modernization challenges facing today's power utilities. In particular, the need to implement new, smart solutions to manage the growing number of DERs often requires expensive upgrades to existing systems (e.g., SCADA).
With the widespread adoption of distributed energy resources (DERs), the modern grid is becoming an increasingly complex network of interconnected systems.
With the proliferation of DERs - such as rooftop solar panels, consumer and grid-level storage batteries, and wind turbines – utilities' storage network management requirements are becoming more complex.
As governments continue to invest in green technologies and encourage the use of renewable energy sources, more and more households are installing solar panels on their rooftops. In many countries, local and national regulations stipulate that any household that wants to install rooftop panels can do so, and that the utility must connect the rooftop system to the grid.
Five years ago, dissolved gas analysis (DGA) was like getting a blood test at your annual physical. The transformer expert drew a sample of oil once every three to six months, sent it to the lab for analysis, and then anxiously waited for the results.
Dissolved Gas Analysis (DGA) is one of the most important monitoring tools power utility companies can embrace. As the new realities of power usage are more demanding than ever, ensuring the health of power transformers becomes more challenging. However, DGA on its own doesn't provide an answer to the monitoring needs of the modern power facility. Relying on DGA without addressing its limitations can be as disastrous as not having DGA at all.
