The benefits brought to electric power systems by reactive power stati
c compensation are well known. Further benefits can arise when an inde
pendent active power compensation and a reactive one are carried out t
ogether, especially if the electronic apparatus can be controlled rapi
dly. Independent and rapid control of both active and reactive power c
an be achieved by convertors with biparametric regulation, whose behav
iour is strongly influenced by their AC power system interactions and
which can work in nonideal conditions such as those arising from volta
ge harmonics and unbalances. This paper presents mathematical models o
f convertors with biparametric regulation with a view to carrying out
a complete analysis in steady-state nonideal conditions; the models ar
e developed so that they are applicable for studies both at fundamenta
l and at harmonic frequencies. Numerical applications to convertors co
nnected to a superconducting coil for energy storage are also discusse
