Abstract: A method for obtaining an improved transformer design for a power plant, comprises the steps of defining one or more critical temperatures (θhwnormal, θhwcontingency, θh, θo) in the operation of the transformer, determining a limit (θhw,max normal, θhw,max contingency, θh,max, θo,max) for at least one of the critical temperatures and obtaining an adjusted design of the transformer by using a data set of transformer loading, the data set comprising the amount of time (H) at a specific load level (κ) for a specific ambient temperature (θa). The method further comprises the step of producing a transformer having the adjusted values of the design parameters (Δθhr, Δθor, R, x, y) and/or using a transformer having the adjusted values of the design parameters (Δθhr, Δθor, R, x, y) in the power plant.

Abstract: A system determines a location and a size of a new power generation or power regulating unit within a current system architecture of a power system including a plurality of power generation units. The system comprises a controller including a processor and a memory, computer-readable logic code stored in the memory which, when executed by the processor, causes the controller to execute a hybrid algorithm as a combination of a data-driven algorithm and a model-based algorithm to determine an optimal location and size of the new power generation or power regulating unit. The data-driven algorithm encodes a location and a size information. The controller to enable the model-based algorithm to optimize performance of a selected location and size of the new power generation or power regulating unit, which is based on a linearized system or a nonlinear system to provide guidance for the data-driven algorithm to incorporate physical rules and verify a new system architecture.
