摘要： In Kazakhstan, a number of measures have been taken to stimulate the introduction of renewable energy, one of which is solar energy [1], [2]. Until 2025, the introduction of solar power plants (SPP) will be 650 MW. When integrating solar panels with inverter coupling into electrical networks, a number of difficulties arise related to the stability of the voltage in transient modes. The converter voltage inverters do not have feedback from the voltage of the external power supply system. Power generation of SPP, as a rule, is only a function of solar radiation and does not depend on the network parameters [3]. In this regard, the actual issue is the introduction of adaptive controllers for controlling inverters, depending on the change in the mode parameters [4], [5]. In this paper, we present the results of studies on the modeling of transient regimes using the example of the SPP with an installed capacity of 2 MW. The virtual model of the PSCad analyzed the stability of the voltage in the event of a short circuit on the 10 kV bus, algorithms and mechanisms for using the intelligent controller for controlling the photovoltaic system were developed.
