The system can be used for simulating the electromechanical transient state or the electromagnetic transient state of the power system in real time respectively, and can also be used for simulating an electromechanical transient state and electromagnetic transient state hybrid system in real time. And the ADPSS adopts 64-bit double-precision floating point number operation in the real-time simulation process, the simulation precision is high, and the simulation precision is equivalent to that of the acknowledged offline analysis software MATLAB. As a commercial PC Cluster-based hardware architecture is directly adopted, when the simulation scale of the power grid is increased, only the number of CPUs (central processing units) is increased and the memory capacity is increased, and the system has better application in the aspects of upgrading, expanding flexibility and the like.
At present, the following problems exist in the planning and operation management of the micro-grid: when the ADPSS is needed to be used for simulating the microgrid planning scheme, the SIM model file of the microgrid planning scheme cannot be directly used by the ADPSS, so that the SIM model file needs to be manually converted into an intermediate file meeting the ADPSS format requirement, and the simulation model is generated by the ADPSS through the intermediate file, so that the cost of manpower and material resources is increased, and the generation efficiency of the simulation model is low.
