Valorization of demand response for voltage control in MV distribution grids with distributed generation

Abstract

This paper presents a methodology for the contribution of demand response in reducing the cost of voltage control in radial distribution grid with distributed generators (DG). The bidirectional power flow in the active distribution network can introduce voltage issues that impede the integration of DG. Due to this fact, the distribution system operator (DSO) has to enhance the lines in the grid or curtail the power output of DG in case of constraint. The possibility of using the flexibility of demand to cope with the voltage constraint is investigated in this paper. The results are promising that by using the demand response, it is able to reduce the active curtailment of DG and postpone the investment of grid reinforcement.

Demand response scheduling to support distribution networks operation using rolling multi-period optimization

“…The total demand on the feeder is up to 9.52MW. The detailed characteristics of this test network can be found in [29]. The RES connected in this feeder include WT and rooftop PV.…”

Impact of consumer profiles and forecast accuracy on day-ahead scheduling of household appliances

“…A high penetration of distributed generators (DG) on low-voltage grids triggers the need either to enhance the grid infrastructure or to occasionally curtail the renewable production. Authors in [3] showed how demand response (DR) can help control voltage in distribution grids with high DG penetration, by decreasing the power exchanged with the grid. In this way, demand response can reduce the need for grid reinforcement in spite of a high PV penetration rate.…”
