Renewables and the Grid: Friends, Not Enemies

Presentation Description: Renewable resources have been viewed as having a negative impact to the grid, but things are changing. With good grid modelling powered by rich data, and active control, renewable generations - especially utility-scale renewable generations - can play a positive role in supporting the grid.
Detailed models of the T&D network and renewable generation will allow more realistic scenarios and predictions. Combined with rich data from AMI and SCADA systems, and automated load flow analysis, the grid operator can see the full picture and make the best decisions. If we can integrate DERMS or ADMS, utilities will be enabled with controllability to leverage renewable sources to support grid health, which can generate technical and commercial benefits to the generation owner and the entire customer base.
Utility-scale energy storage systems are already supporting grid stability in some parts of the world. For example, the first phase of the total 200MW utility-scale battery storage is deployed in Singapore. These centralized energy storage systems are fully controlled by the utility to support grid stability, manage supply and demand, and mitigate intermittency.
