Parameter determination method and system for microgrid simulation model

Abstract

The embodiment of the invention discloses a parameter determination method and system for a microgrid simulation model. The method comprises the following steps: carrying out a test on a sub-module ofequipment to be tested to determine test data, carrying out parameter identification according to the test data, generating an identification parameter set, carrying out a verification test on a microgrid according to a preset verification test scheme, and determining verification test data, wherein the micro-grid is composed of a plurality of equipment to be tested, the same simulation test is carried out on the micro-grid simulation model according to the verification test carried out on the micro-grid based on the identification parameter set to obtain the simulation test data of the micro-grid, and the parameters of the micro-grid simulation model are adjusted according to the verification test data and the simulation test data. According to the technical scheme provided by the embodiment of the invention, the problem of relatively high production cost of the microgrid due to the fact that input parameters and output parameters of different electrical equipment of the microgrid are difficult to consider in an existing parameter determination method for the simulation model of the microgrid is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of micro-grids, and in particular, to a method and system for determining parameters of a simulation model of a micro-grid. Background technique [0002] Digital simulation technology plays an indispensable role in the important planning of micro-grid, such as system power flow calculation, short-circuit current calculation, stability analysis, various fault ride-through capability verification, and even the final control algorithm and scheduling strategy. . Before the microgrid equipment is put into production, it is necessary to simulate the input parameters and output parameters of the equipment in the microgrid. The existing method for determining the parameters of the simulation model of the microgrid is difficult to take into account the input parameters and output parameters of different electrical equipment in the microgrid, resulting in The commissioning cost of microgrid is r...
