An analytical method was utilized to determine the optimal amount of compensating capacitors in the first stage, while a statistical approach was employed to assess the reduction in energy losses resulting from the capacitor placement in each of the network nodes.
This article presents an efficient voltage regulation method using capacitive reactive power. Simultaneous operation of photovoltaic power systems with the local grids induces voltage instabilities in the distribution lines. These voltage fluctuations cross the allowable limits on several occasions and cause economic losses.
It is clear that the line active and reactive power flows based on fixed and switched capacitors are lower than those obtained in the case of without capacitors. In addition, the directions of reactive power flows are reversed in nine lines for fixed capacitors and in seven lines for switched capacitors.
In [111, 112], a two-stage method was used to solve the optimal capacitor placement problem. First, the power loss index (PLI) in and the LSFs in were utilized to determine the high potential buses for capacitor placement.
There is a novel method to actively compensate for the reactive current caused by the EMI capacitor. Moreover, the PFC current-loop reference is reshaped at the AC zero-crossing to accommodate for the fact that any reverse current will be blocked by the diode bridge. Both PF and THD are improved as a result. Figure 3.
The proposed method for EMI-capacitor compensation uses this red waveform as its current reference. In theory, if the PFC current loop uses this as its reference, the EMI-capacitor reactive current can be fully compensated, and the PF can be increased. The proposed current reference is further improved as shown in Figure 5.
