An Optimal Strategy for Short Circuit Current Limiter Deployment

Abstract

An optimization model for deploying short circuit current limiters is presented. The problem is modelled as a 0-1 mixed integer programming problem. The mathematic model is solved by a discrete particle swarm optimization algorithm (DPSO). The results of a 107-bus system in East China are provided to validate the possible applications of the proposed method.

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

“…Furthermore, the lower and upper limits of nodal voltage are 0.95 and 1.1 p.u., respectively. Cost coefficients of FCL can be found in [33]. In order to realise the coordination between the FCL dynamic response process and the action time of relay protection components, we choose two types of FCL with different time constant.…”

Coordinated optimization for controlling short circuit current and multi-infeed DC interaction

“…where N s is the number of put-into current limiting measures; u s = 1 represents that the measure s is put into and u s = 0 represents that the measure s is not put into; k as and k bs are the cost factors of the measure s [13]; z s is the reactance value of the current limiting reactor or the short circuit voltage percentage increment of the high-impedance transformer.…”

“…The minimum multi-infeed shortcircuit ratio is set to 2.0 [18]. The cost factors of opening the line are as follows: k as = 60, k bs = 0, and the cost factors of installing the current limiting reactor are as follows: k as = 625, k bs = 25 [13]. The structure of regional power grid in China is shown in Fig.…”

“…Reference [12] presented a method with genetic algorithm and particle swarm optimization to find the optimal location and the number of buses to be split. In [13], the optimization problem was modeled as a 0-1 mixed integer programming problem, and the model can be solved by a branch and bound algorithm to generate optimal current limiting strategies.…”

Transmission network expansion planning with embedded constraints of short circuit currents and N-1 security

“…In the past decades, how to reduce short circuit currents of power grids has been widely investigated [8][9][10][11][12]. Up to date, there are mainly three kinds of measures in limiting short circuit currents, i.e., to improve the structure of power grids, to optimize the operation of power systems and to deploy current limiting devices.…”
