Systems engineering
When you look at Moné’s [1] definition for the Levelized Cost of Energy (LCoE),
\[LCoE = \frac{\left( CapEx \cdot FCR \right) + OpEx}{AEP_{net} }\]
with:
- \(LCoE\)
- levelized cost of energy \(\left[ \frac{ \text{€} }{ \text{kWh} } \right]\)
- \(CapEx\)
- capital expenditures \(\left[ \frac{ \text{€} }{ \text{kW} } \right]\)
- \(FCR\)
- fixed charge rate [%] (a financial term, not further discussed here).
- \(OpEx\)
- annual operational expenditures \(\left[ \frac{ \text{€} }{ \text{kW} \cdot \text{yr} } \right]\)
- \(AEP_{net}\)
- net annual energy production \(\left[ \frac{ \text{kWh} }{ \text{kW} \cdot \text{yr} } \right]\)
you see that it contains four terms. Three of them depend on engineering:
- The \(CapEx\) is directly linked to the cost of your product,
- The \(OpEx\) to your product’s reliability
- and the \(AEP_{net}\) to performance.
These three aspects are representing the Cost, Performance & Reliability of functions linking sales to designed wind turbine components. The way to manage these aspects throughout the product life-cycle is by deploying Systems Engineering to Product Life-cycle Management (PLM).
We provide support, guidance and on-the-job training to wind turbine OEM by using various Systems Engineering methods.
