Supervised model predictive control of large‐scale electricity networks via clustering methods

چکیده
This article describes a control approach for large-scale electricity networks, with the goal of efficiently coordinating distributed generators to balance unexpected load variations respect nominal forecasts. To mitigate difficulties due size problem, proposed methodology is divided in two steps. First, network partitioned into clusters, composed several dispatchable and nondispatchable generators, storage systems, loads. A clustering algorithm designed aim obtaining clusters following characteristics: (i) they must be compact, keeping distance between loads as small possible; (ii) able internally maximum possible extent. Once has been completed, layer system designed. At lower layer, local model predictive controller associated each cluster managing available generation elements compensate variations. If sources are not sufficient cluster's variations, power request sent supervisory which optimally distributes additional resources from other network. enhance scalability approach, supervisor implemented relying on fully optimization algorithm. The IEEE 118-bus used test design procedure nontrivial scenario.

Semi-supervised clustering methods
Cluster analysis methods seek to partition a data set into homogeneous subgroups. It is useful in a wide variety of applications, including document processing and modern genetics. Conventional clustering methods are unsupervised, meaning that there is no outcome variable nor is anything known about the relationship between the observations in the data set. In many situations, however, informat...
متن کاملInventory Control by Model Predictive Control Methods
This paper describes a model predictive control strategy to tackle the inventory control problem in Supply Chains. The problem is formulated as a receding-horizon optimization problem and the market demand is considered an external unknown disturbance. The behaviour of the Supply Chain is modelled by discrete time difference equations, both the control variables and the output variables are con...

متن کاملSet Theoretic Methods in Model Predictive Control
The main objective of this paper is to highlight the role of the set theoretic analysis in the model predictive control synthesis. In particular, the set theoretic analysis is invoked to: (i) indicate the fragility of the model predictive control synthesis with respect to variations of the terminal constraint set and the terminal cost function and (ii) discuss a simple, tube based, robust model...
