Embodiment 1
[0100] The energy management system EMS mainly provides grid dispatchers with various real-time information of the grid, including: frequency, generator power, line power, bus voltage, etc., and conducts scheduling decision-making management of the grid to realize centralized monitoring and control of power production and transmission , to ensure the safe, high-quality and economical operation of the power grid. The power system needs to realize real-time / ultra-real-time EMS, and all calculations need to be completed within the sampling time, which generally includes two types: transient calculation and steady-state calculation. The core of steady-state calculation is power flow calculation. At present, power system applications are mainly implemented on the CPU, but power flow calculations have very fine-grained parallelism, which is not supported by general-purpose CPUs and cannot meet real-time requirements.
[0101] An annotated power flow distribution graph is a directed ...
