Multi-objective optimal configuration of current limiting strategies

Risk‐based many‐objective configuration of power system fault current limiters utilising NSGA‐III

“…The SCC at bus b can be calculated as follows: According to (10), the fault current limiting can be achieved by modifying the bus admittance matrix. The SCC decreases as the self‐impedance of the corresponding buses increases [2]. If only the impedance of branch l (line i – j ) is added by Δ x l .…”

“…Short‐circuit is one of the most common fault types in power systems [1]. With the interconnection and expansion of power grids, short‐circuit currents (SCCs) are increasing significantly [2]. The problem of out‐of‐range SCC has been a prominent concern in many countries, especially in China [3].…”

“…Besides the SCC, SCF has multiple impacts on power system operation [17]. For instance, when an SCF occurs or a certain FCL is deployed in the grid, the system stability boundary changes [2, 7]. Consequently, the stability influence of SCF has been widely considered in the FCL configuration.…”

Multi-objective pigeon-inspired optimization for brushless direct current motor parameter design

“…Pareto sorting scheme has been involved in many algorithms to deal with multi-objective optimization problems, such as NSGA-II [19,[21][22][23], MOPSO [8] and BA [6]. In NSGA-II, the initial population evolves to obtain a population of genotypes and a set of the phenotypes of these genotypes [24].…”

Circuit model based design and analysis for a four-structure-switchable wireless power transfer system

“…Modeling and optimization are scientific methods, which are widely used in many researches [17][18][19][20], and at present, the model of WPT system is established commonly using the circuit theory, which is through building up the equivalent parameters of the system physical model to analyze. In this paper, we adopt this theory for our systems modeling to study the transfer property of different structures.…”
