Stochastic Distributed Control for Arbitrarily Connected Microgrid Clusters

Energies, 2022
Due to the success of single microgrids, the coming years are likely to see a transformation of the current electric power system to a multiple microgrid network.

Stochastic control with state constraints via the Fokker–Planck equation. Application to renewable energy plants with batteries

Comptes Rendus. Mécanique
Although renewable energies are beneficial to reduce carbon emissions, its intermittent characteristics may result in power-supply issues in distribution grid. Battery energy storage system is generally regarded as an effective tool to deal with them. On

A Deterministic Setting for the Numerical Computation of the Stabilizing Solutions to Stochastic Game-Theoretic Riccati Equations

Mathematics, 2023
In this paper, we are interested in the numerical aspects of the class of generalized Riccati difference equations which are involved in linear quadratic (LQ) stochastic difference games.

Stochastic Power Control Strategy for Hybrid Electric Propulsion Ships Using Markov Chain-Based Operational Data Augmentation

Journal of Marine Science and Engineering
Since power demand varies due to uncertain environmental conditions, a deterministic power control strategy for hybrid electric propulsion ships contains a limitation in securing robust performance.

Company Value with Ruin Constraint in Lundberg Models

Risks, 2018
In this note we study the problem of company values with a ruin constraint in classical continuous time Lundberg models. For this, we adapt the methods and results for discrete de Finetti models to time and state continuous Lundberg models.

Optimal Dividend Payment in De Finetti Models: Survey and New Results and Strategies

Risks, 2020
We consider optimal dividend payment under the constraint that the with-dividend ruin probability does not exceed a given value α. This is done in most simple discrete De Finetti models.

Stochastic Modelling and Self Tuning Control of a Continuous Cement Raw Material Mixing System [PDF]

Modeling, Identification and Control, 1980
The control of a continuously operating system for cement raw material mixing is studied. The purpose of the mixing system is to maintain a constant composition of the cement raw meal for the kiln despite variations of the raw material compositions ...

Efficient Sensitivity-Based Cooperation Concept for Hierarchical Multilayer Process Automation of Steam-Powered Plants

IEEE Access, 2022
Hierarchical optimization architectures are typically employed to manage industrial steam processes efficiently. The key challenge today is to find a near global optimum despite these subdivided automation structures.

Assessment of Policy Changes to Means-Tested Age Pension Using the Expected Utility Model: Implication for Decisions in Retirement

Risks, 2017
Means-tested pension policies are typical for many countries, and the assessment of policy changes is critical for policy makers. In this paper, we consider the Australian means-tested Age Pension.
