Implementation of a feature selection algorithm in FARM to identify important state variables and time-invariant matrices

“…In this work, the same two-component test case reported in [6] and [7] is used. As shown in Figure 3-1, the IES unit is composed of a Secondary Energy Source (SES) and a Balance of Plant (BOP).…”

Integration of Control Methods and Digital Twins for Advanced Nuclear Reactors

“…If supervisory AI/ML control is used, a means of coupling those methods with either HP or logical control must be developed, as discussed in Section 4.1.3. For example, methods are being developed for integrating low-level controllers (e.g., PIDs) designed for system stability with a reference governor control algorithm to enable the desired dispatch of electricity control [92] [93].…”

Application of FARM to an IES scenario within the FORCE ecosystem

“…In July 2022, the latest version of FARM (FARM-Delta) was released [9]. The major improvement consists in the implementation of a single MIMO (Multiple-Input Multiple-Output) RG coordinating the different subsystems that constitute the IES unit (Figure 1-7).…”

“…Every time the power set-points are adjusted by HERON, this algorithm solves a Quadratic Programming (QP) problem to find a vector of set-points within the Maximum Output Admissible Region (MOAS) that minimizes the geometric distance to originally issued set-points, and automatically addresses the couplings between IES components. For more details the reader may refer to [9]. In Figure 1-7, the workflow of FARM-Delta validator is shown.…”

“…The k-nearest neighbors classifier is then re-trained to refine the mapping of set-point levels to matrices. More details about the system identification approach adopted in FARM-Delta can be found in [9].…”
