TL;DR: This study proposes a mixed-integer linear programming-based expansion planning model for DNs considering the impact of high RES and PEV penetration, the associated uncertainties, and providing flexibility requirements at the distribution level, and implements the spherical simplex unscented transformation in this respect.

TL;DR: In this paper, the authors describe the hardware and software to perform voltage phase angles at busses of the power network, using the Global Positioning System (GPS) absolute timing reference.

TL;DR: In this article, the authors investigated the potential of mitigating wind generation curtailment via aggregating the domestic electric storage heaters and showed that aggregating domestic thermal storages is a viable option for curtailment mitigation, but with the indispensable caution that mitigation potential significantly saturates as the share of wind generation escalates beyond a certain limit.

TL;DR: In this paper, a sensor for fast transients measurements is presented and tested, and the results of performance verification measurements show very good results when testing with high-frequency pulse source, presenting the potential of such sensor.

TL;DR: In this article, a block-layer method for the reliability assessment of distribution systems is proposed, which is based on three critical parts of the distribution system: main supply, feeder, and secondary substation.
