The invention relates to an exhaust-gas-turbocharged internal combustion engine, which comprises at least two turbines and switchable air outlets, and an operation method thereof. Systems and methods are provided for controlling boost pressure in an engine system with a parallel turbocharger. One example method includes, responsive to a first condition, deactivating a first compressor of a first turbocharger, activating each first exhaust valve of each cylinder of an engine, and deactivating each second exhaust valve of each cylinder of the engine to flow exhaust gas from the engine to a second turbocharger. The method further includes, responsive to boost pressure exceeding a threshold, maintaining deactivation of the first compressor, reactivating each second exhaust valve to flow exhaust gas from the engine to both the first turbocharger and second turbocharger, and driving an electric assist device via a first turbine of the first turbocharger.
