MITIGATING IMPACT OF LARGE-SCALE PV INTEGRATION ON MV DISTRIBUTION NETWORK WITH SEQUENTIAL CONTROL FUNCTIONS: A CASE STUDY IN NOORDWOLDE GRID, THE NETHERLANDS

Abstract

In this paper, the voltage violation problem that might arise from the integration of a large-scale PV system into a distribution network in Noordwolde, the Netherlands is investigated. Subsequently, a sequential control scheme is proposed that coordinates reactive power absorption and active power curtailment of PV inverter to mitigate such problem. The proposed control is locally performed at the inverters and does not require an extensive communication system. Its performance is compared with the control scheme employing only reactive power absorption or active power curtailment. The feasibility of the proposed control is successfully verified through simulations on Noordwolde medium voltage network using Vision Network Analysis along with data measurements in the field.
