Power grids exhibit patterns of reaction to outages similar complex networks. Blackout sequences follow power laws, as systems operating near a critical point. Here, the tolerance electric both accidental and malicious is analyzed in framework network theory. In particular, quantity known efficiency modified by introducing new concept distance between nodes. As result, parameter called net-ability proposed evaluate performance grids. A comparison provided estimating vulnerability sample...
Power system vulnerability is a key concern in modern societies and many efforts have been devoted to its analysis. Recently, the wide domain of complex networks that can be used assess network systems has applied power grids as well with focus on topological transmission based structure terms nodes their connection patterns. However, pure approach, proposed current literature, fails capturing specific features systems. The authors propose an extended which incorporate several important such...
With the increasing penetration of renewables in power system, frequency regulation is becoming a big challenge for conventional coal-fueled thermal generator units. To address this issue, more stringent criteria automatic generation control (AGC) has been established by grid operators to regulate generators. However, old-fashioned units can hardly meet requirements and thus are subject penalty. In paper, an approach using battery energy storage systems (BESS) coordinated proposed improve...
Rail transportation is used extensively in urban areas to reduce CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission and increase road capacity. As a result, the energy efficiency of rail becoming popular research topic. Energy-efficient train operation involves four types control: maximal traction, cruising, coasting, braking. With rapid development storage devices (ESDs), this paper aims develop an integrated optimization model...
