PROJECT TITLE :
Optimal Distribution Network Automation Considering Earth Fault Events
Within the past decade, distribution network operators are broadly engrossed toward automated distribution networks. The operators acknowledge network automation as an economical investment toward a better service reliability. This paper aims to supply a replacement long-term value/profit analysis for an optimal level of distribution network automation. Within the analysis, reduction in customer outage value is considered as the advantage of implementing automation systems with capital investment, and annual operation and maintenance costs. Within the Finnish regulation model, there's a special incentive primarily based on client outage price reduction. As the most contribution of this paper, the impact of earth fault events and their needed time-consuming fault management process is taken into account inside the calculation of the advantage of automation systems. The answer of the analysis consists of the optimal number and site of remote-controlled sectionalizing switches, which are building blocks of automation systems. The problem is formulated in an exceedingly mixed-integer linear programming format that may be effectively solved by commercially obtainable solvers. The effectiveness of the proposed algorithm is demonstrated by applying it to the Helsinki distribution network. The results show that neglecting the impact of earth fault events can lead to suboptimal solutions.
