Increasing solar PV hosting capacity in distribution feeders with intelligent and fair curtailment schemes

Abstract

Residential solar PV is being deployed at record-setting pace, which is in part driven by decreased costs and increasing environmental concerns. However, too much solar PV in certain locations and at certain times can impact reliability in distribution systems. To overcome this, distribution system operators have developed conservative hosting capacity ratings for feeders based on worst-case grid and PV conditions. Thus, this paper focuses on intelligent curtailment strategies that increase hosting capacity while accounting for live grid conditions and equitable participation. The methods presented center around local solar PV curtailment budgets (to prioritize and equalize participation).
