The increasing integration of renewable resources and electric vehicles (EVs) presents new requirements for the construction a current distribution network. As an alternative conventional network, active network (ADN) has gained more interest its flexibility interactivity. However, unpredictable behavior ADN participants from source-side, network-side, demand-side brings challenges on dispatch. Thus, it is urged to design optimal scheduling approach that can comprehensively regulate...

Repair crews (RCs) and mobile power sources (MPSs) are emergency resources (EMRs) for distribution system repair restoration. In this paper, an outage management strategy (OMS) is proposed to improve the resilience against extreme weather events in both preventive post-disaster stages. stage, considering uncertainty of fault location, resource allocation problem formulated as a two-stage stochastic programming minimize expected load shedding cost shortly after disaster. The stage cooperative...

Uncertainties on both the source and de-mand side pose challenges for day-to-day management of distributed power systems, such as microgrids (MGs). To harness potential flexible scheduling within MGs to explore economic environmental advantages cooperative interactions between multiple MGs, this paper develops a two-stage power-sharing model day-ahead intraday operations across multi-MGs. The stage, which takes into account prediction errors caused by uncertainty, refines results factoring...

Because of the rapid development electric vehicles (EVs), energy management multimicrogrid (MMG) systems has attracted considerable research attention. The objective this study is to coordinate scheduling performance for MMG under large-scale EV operations. To address problem that calculation time increases exponentially with scale EVs, a clustering algorithm was proposed speed up solving efficiency coordinated systems. departure and arrival times crossover among various MGs, set boundary...

In modern power systems, the stochastic and interactive characteristics of mixed generations have gained increasing interest, especially when more renewable energy sources are connected to grid. The uncertainty has notable effects on system security. this paper, a set composite security indices, which derived from Hyper-box Hyper-ellipse Space theory, extended by Latin hypercube sampling method model multiple probabilistic scenarios under uncertainty. Thus, proposed approach is suitable for...
