dcterms.abstractDistributed energy resource (DER), such as rooftop photovoltaics (PV), provide clean energy to the grid and have the potential to improve the grid efficiency. On the other hand, DER left unregulated can cause over-voltages and dangerous levels of reverse power flow. This paper proposes resistive load dumps to be placed at the low-voltage nodes of distribution circuits to equitably regulate the voltage and reverse current. The low-cost resistive devices require limited knowledge of the distribution system and are operated using local measurements, which minimizes the overall cost of the system. The basic profit models developed in this paper suggest curtailing real power to regulate voltage with load dumps could be economical. Local measurement based strategies are introduced to operate the load dumps, and placement and sizing heuristics are proposed when there is limited distribution circuit knowledge. The load dumps are shown to eliminate over 99% of the over-voltages by curtailing only 5% of the PV generation during a simulated year of operation on a synthetic distribution circuit model.
