Merging top-down and bottom-up planning approaches

This weblog sequence discusses the advanced duties power utility firms face as they shift to holistic grid asset administration to handle via the energy transition. The primary submit of this sequence addressed the challenges of the power transition with holistic grid asset administration. The second submit on this sequence addressed the built-in asset administration platform and knowledge trade that unite enterprise disciplines in numerous 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 numerous planning administration methods supplies optimization alternatives on three ranges:

1. Asset portfolio (AIP) stage: Optimum undertaking execution schedule
2. Asset (APMO) stage: Optimum upkeep and substitute timing
3. Spare half (MRO) stage: Optimum spare components 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 prospects and long-term grid necessities. Asset funding planning (AIP) instruments deliver worth in optimizing numerous, generally conflicting, worth drivers. They mix new asset investments with current asset replacements. Nevertheless, they comply with totally different approaches to danger administration by utilizing a danger matrix to evaluate danger firstly of an optimization cycle. This top-down course of is efficient for brand spanking new belongings since no details about the belongings is out there. For current belongings, a extra correct bottom-up danger method is out there from the continual well being monitoring course of. This course of calculates the well being index and the efficient age based mostly on the asset’s particular degradation curves. Dynamic well being monitoring supplies up-to-date danger 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 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 methods load these duties for execution by subject service departments.

On the upkeep restore and overhaul (MRO) aspect, spare half optimization is linked to asset criticality. Failure mode and impact evaluation (FMEA) defines upkeep methods and related spare holding methods. The primary parameters are optimizing for inventory worth, asset criticality and spare half ordering lead instances.

Conventional planning processes concentrate on disparate planning cycles for brand spanking new and current 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 leads to decrease outages and system downtime, and it will increase the environment friendly use of scarce assets and funds.
