This paper introduces a dc transmission grid with fault-tolerant inductor-capacitor-inductor (LCL) voltage-source converters (VSCs) and using slow protection system based on mechanical circuit breakers (CBs). LCL VSC inherently regulates fault current to levels that can sustain for prolonged periods which avoids insulated-gate bipolar transistor tripping brings significant advantage security reliability aspects. Simple CBs are used at busbars connecting points of each cable, in the same...
Transfer capacities of urban distribution networks need to be increased fulfill the increasing load demands and accommodate distributed generation (DG). However, there are limited spaces build new substations lines, curtailment DGs may happen due voltage violation during DG outputs fluctuation. This paper proposes analyzes various methods convert some existing ac MV lines dc in order form a hybrid ac/dc network, based on which transfer can increased, flexible power shift achieved through...
In recent years, the frequent occurrence of extreme natural disasters has caused huge economic losses, which makes it extremely important to improve resilience distribution networks. With increasing penetration DC sources and loads, urban network is transitioning from AC hybrid AC/DC configuration that can operate in a ring structure. The features flexible interconnections low losses lines break bottleneck traditional restoration methods for networks under disasters, thereby further...
The flexible AC/DC interconnection of low-voltage distribution networks (LVDNs) using soft open points (SOPs) enhances load-carrying capacity and distributed generation (DG) accommodation capability through optimal power shifting considering the complementarity between LVDNs. However, degree interconnected LVDNs is usually affected by periodic change load power, current fixed scheme plays a significant role only during some periods, resulting in low utilization rate equipment. To tackle this...
The large-scale integration of renewable energy sources and new loads, such as distributed photovoltaics electric vehicles, has resulted in frequent power quality issues within distribution networks. Traditional AC networks lack the necessary flexibility have limited capacity to accommodate these loads. Transforming conventional network into an AC-DC hybrid using flexible interconnection devices like Voltage Source Converters can enhance network’s flexibility, mitigating challenges arising...
The fault current in MMC HVDC systems suffers from a quick rising rate and no zero-cross problems, which makes it hard to cut off has become the main problem when promoting dc systems. Among different types of faults, pole-to-pole is most serious one. Hence, clarify discharging mechanism during faults determine influential factors, this paper proposes simplified modeling method for impact factors analysis. proposed uses circuit happen, frequency domain model then established Considering that...

Exploring differences within basin key entry point solving dilemma governance Basin, optimizing allocation resources, improving overall effectiveness...
Abstract Cyclic adenosine monophosphate (cAMP) plays an important role in many biological processes as a second messenger and cAMP treatment has been reported to extend the lifespan of wild-type Drosophila melanogaster . Our study showed that exogenous improved ageing-related phenotypes by increasing protein level Sirtuins, which prevented metabolic disorders mimic effect calorie restriction. Experiments vitro directly bound SIRT1 SIRT3 consequently increased their activity. These findings...
To mitigate the voltage violation and overloading caused by integration of Distributed Generation (DG) Electric Vehicle Charging (EVC) loads, a feasible solution is to convert some AC medium distribution lines DC ones formulate an AC/DC hybrid network, based on which flexible power shifting between can be achieved. However, complementarity flows amongst hardly described embedded in existing configuration optimization methods only average loading or variations for certain period considered....
