Equivalent Modelling of Hybrid RES Plant for Power System Transient Stability Studies

The paper proposes methodology for development of dynamic equivalent model hybrid renewable energy source (HRES) plant suitable reliable assessment the overall transient stability realistic, large power systems. Transient index is used system assessment, and consequently evaluation performance. historical production data transmission network short-circuit fault statistics, together with probabilistically modelled uncertainties associated operation, are to generate a set realistic responses over period one year. use clustering algorithms enabled unsupervised grouping/clustering low order models in form transfer function voltage as an input real reactive outputs. illustrated on number case studies using two HRES configurations. It demonstrated that very few can be during year sufficiently accurate system. possibility deriving these based forecasted composition makes them attractive practical application security studies.
