Abstract: With the rapid development of renewables, DC transmission, and active loads, increasingly more power electronics are and will be introduced into power grids. This has led to an increasing need for a new synchronized measurement system that covers different scenarios and applications to improve the stability and reliability of power-electronics-enabled power grids. Therefore, a full-view synchronized measurement system (SYMS) for renewables, loads, and grids is established by our group, which is composed of different types of synchronized measurement devices (SMDs) and a data center. A general design method for synchrophasor estimation of the SMDs in different scenarios is proposed by deducing phasor measurement error models. This is further applied in combination with the design of hardware and a communication protocol to develop SMDs for the measurement of the renewables, loads, and power-electronics-enabled power grids. Then, the framework of the data center of the SYMS, as well as several potential applications based on real-time measurements, are presented and discussed.
