- Distribution grid dynamics has been changing dramatically, from up to hour long of human involved control actions, to seconds, even down to millisecond, with the increasing presence of DER technologies such as solar PV and power electronics for inverters.
- Coping with such fast grid dynamics, especially in areas with high penetration of DER is an important criterion for choosing a reliable DMS/DERMS system. The solution should be capable of executing online Distribution Power Flow (DPF), Distribution state estimation (DSE), and control actions including DERs according to local regulations. The system target will be to increase hosting capacity and avoid congestion of distribution and transmission grid in a pro-active manner.
- For example, there are customers in Europe, operating distribution grid in an area same as Greater Toronto Area, or half of Greater Los Angeles Area, with more than 30,000 DER under monitoring, control and management of grid control centre for several years.
- Handling such a massive data stream in DMS/DERMS control center, and fulfilling online network applications, is a task should be done with certain level of reliability, flexibility, and performance.
