This weblog sequence discusses the advanced duties power utility firms face as they shift to holistic grid asset administration to handle by the power transition. The primary publish of this sequence addressed the challenges of the power transition with holistic grid asset administration. The second publish on this sequence 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 strategy that mixes the siloed processes and integrates numerous planning administration techniques supplies optimization alternatives on three ranges:
Asset portfolio (AIP) stage: Optimum undertaking execution schedule
Asset (APMO) stage: Optimum upkeep and substitute timing
Spare half (MRO) stage: Optimum spare elements holding stage
The mixed planning workouts 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 usually a part of a grid planning division, which considers expansions, load research, new clients and long-term grid necessities. Asset funding planning (AIP) instruments carry worth in optimizing numerous, generally conflicting, worth drivers. They mix new asset investments with current asset replacements. Nevertheless, they observe totally different approaches to danger administration through the use of a danger matrix to evaluate danger at the beginning of an optimization cycle. This top-down course of is efficient for brand spanking new property since no details about the property is accessible. For current property, a extra correct bottom-up danger strategy is accessible 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 supplies up-to-date danger knowledge and correct substitute timing, versus the static strategy 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 undertaking planning happen in operations departments. The APMO course of generates an optimized work schedule for upkeep duties over a undertaking interval and calculates the optimum substitute second for an current asset on the finish of its lifetime. The upkeep administration and undertaking planning techniques load these duties for execution by area 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 spanking new and current property in a top-down versus bottom-up asset planning strategy. This strategy 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 assets and funds.
