This weblog collection discusses the complicated duties vitality utility firms face as they shift to holistic grid asset administration to handle by way of the vitality transition. The primary publish of this collection addressed the challenges of the vitality transition with holistic grid asset administration. The second publish on this collection addressed the built-in asset administration platform and knowledge change that unite enterprise disciplines in several domains in a single community.
Breaking down conventional silos
Many utility asset administration organizations work in silos. A holistic method that mixes the siloed processes and integrates varied planning administration programs offers optimization alternatives on three ranges:
Asset portfolio (AIP) stage: Optimum venture execution schedule
Asset (APMO) stage: Optimum upkeep and substitute timing
Spare half (MRO) stage: Optimum spare elements holding stage
The mixed planning workout routines produce budgets for capital expenditures (CapEx) and working bills (OpEx), and set minimal necessities for grid outages for the upcoming planning interval, as proven within the following determine:
Asset investments are sometimes a part of a grid planning division, which considers expansions, load research, new prospects and long-term grid necessities. Asset funding planning (AIP) instruments convey worth in optimizing varied, typically conflicting, worth drivers. They mix new asset investments with present asset replacements. Nevertheless, they observe completely different approaches to threat administration by utilizing a threat matrix to evaluate threat in the beginning of an optimization cycle. This top-down course of is efficient for brand new belongings since no details about the belongings is obtainable. For present belongings, a extra correct bottom-up threat method is obtainable from the continual well being monitoring course of. This course of calculates the well being index and the efficient age primarily based on the asset’s particular degradation curves. Dynamic well being monitoring offers up-to-date threat knowledge and correct substitute timing, versus the static method used for AIP. Combining the asset efficiency administration and optimization (APMO) and AIP processes makes use of this enhanced estimation knowledge to optimize in actual time.
Upkeep and venture planning happen in operations departments. The APMO course of generates an optimized work schedule for upkeep duties over a venture interval and calculates the optimum substitute second for an present asset on the finish of its lifetime. The upkeep administration and venture planning programs load these duties for execution by discipline service departments.
On the upkeep restore and overhaul (MRO) facet, spare half optimization is linked to asset criticality. Failure mode and impact evaluation (FMEA) defines upkeep methods and related spare holding methods. The principle parameters are optimizing for inventory worth, asset criticality and spare half ordering lead occasions.
Conventional planning processes give attention to disparate planning cycles for brand new and present belongings in a top-down versus bottom-up asset planning method. This method results in suboptimization. An built-in planning course of breaks down the departmental silos with optimization engines at three ranges. Optimized planning ends in decrease outages and system downtime, and it will increase the environment friendly use of scarce sources and price range.
