Taking into account static stability of synchronous generators when planning optimizing in-house power plants by reactive power

One problem concerning the design of normal operation is to reduce losses in the active power grid induced by reactive power transmission when generators are running as scheduled. Loss can be reduced by redistributing the reactive power generated by the generators. However, the reactive power of synchronous generators determines their static stability margin and depends on the reactive loads, especially those running at the generator voltage, which limits the control range. This is why it is imperative to optimize the generator configurations for a given range of reactive loads. An algorithm has been developed to optimize in-house power plants by reactive power, which takes into account the reactive loads and the margin of static stability. This is where the novelty of this research lies. When creating the algorithm, sequential equivalentization methods were used to calculate steady-state parameters, to program the parametric optimization, and to perform sequential weighting for static stability analysis. The developed algorithm is the basis of the KATRAN software suit, which can be used to optimize the parameters and analyze the static stability of industrial generators. The software can be used for the optimization of large industrial power centers containing in-house power plants and carrying distributed load.
