MODEL ACTIVE AND REACTIVE POWER FLOW CONTROL OF SINGLE PHASE PARALLEL CONNECTED RENEWABLE ENERGY SOU...

Controllers (UPFC) are the most versatile and complex FACTS enabling accurate and reliable control of both active and reactive power flow over networks, through load sharing between alternative line paths (Song et al , 1999). The origina[r]

It is important to note that except 1, all other approaches
require a hybrid of phase and sequence variables. Keeping this
in view, the objective in this paper is to develop new pie
models for various transformer connections, which will allow
the use of pure phase variable approach. Although this mo[r]
