Integrated solution to target MV cable replacement

Cable Replacement Considering Optimal Wind Integration and Network Reconfiguration

“…Relations (27) and (28) specify constraints on fictitious power flows needed when DG units are connected, whilst radiality constraint is set by (29).…”

“…Consideration of system aspects in replacement planning was first done for ageing transformers, which are arguably the most important components. Hence, the ageing and replacement of cables and transformers was reviewed and classified into four categories: a) Ageing processes in cable [3][4][5][6][7][8][9][10] and transformers [11][12][13][14][15][16]; b) Power system analyses with ageing components [17][18][19][20][21][22][23][24]; c) Replacement of individual/ populations of cable [2,[25][26][27] and transformers [28]- [31]; and d) Cable and transformer replacement based on power system analyses [32][33][34].…”

“…Several methods for replacement of individual cables or cable totals without considering the distribution network have been proposed in [25][26][27]. The life-cycle costing approach in [25] models cable deterioration assuming a linearly varying cable hazard rate over time and investigates different decision options (e.g.…”

“…The model cannot be applied to individual cable sections because it determines the totals of cable replacement. The model and tool from [27] use health indices for transmission cable prioritization and complete a techno-economic study to find the best decisions. However, health indices are calculated from condition data based on online and offline diagnostics which are typically not available in distribution companies.…”
