Abstract

Even though many researchers assume that PV inverters are able to provide reactive power compensation (RPC) at no cost, there are tradeoffs involved in injecting/absorbing reactive power through the inverter.

Notes

  1. 1.

    \(V_{t}^{\text {CAP}}\) is always the same in the simulations done, i.e. \(V_{t}^{\text {CAP}}=V^{\text {INV,DC}}\), and therefore can be taken as constant, and the t index can be removed from \(M_{t}\).

  2. 2.

    This is also partly due to the random allocation of PV systems, instead of installing them at the optimal locations in the system. In fact, the power losses increase after the addition of PV at node 38, 34, and 44.

  3. 3.

    The simulation over at least a year is required to take into account the variation of inverter usage due to different weather conditions throughout the year.
