Abstract: The present invention belongs to the field of smart grids, and relates to a DC voltage adaptive coordinated control system and method under fault of a VSC-HVDC receiving-end power grid. The present invention checks the MSR and compares it with the expected fastest fault clearance time to provide key activation conditions for the active power control of an SEC. When DC overvoltage is prevented, the active power regulation of the SEC and a dynamic brake resistor is reduced by optimizing the control activation thresholds and reference values of the SEC and a REC.

Abstract: A system and method for efficient power analysis of an integrated circuit are described. In various implementations, a memory of a computing system stores combinatorial logic gate-level data describing functionality of a pre-silicon, gate-level representation of the integrated circuit being designed. The circuitry of the processor accesses this data, and also divides the integrated circuit into portions based on functionality. The circuitry of the processor generates first power estimation values over time for a selected first portion by executing a power estimation tool on the first portion. Afterward, the circuitry of the processor trains a data model, such as a neural network, using the generated first power estimation values. The circuitry of the processor then generates second power estimation values over time for one or more other portions by executing the data model on these portions.
