Abstract: This study focuses on CO2 storage by investigating CO2 flow in deep underground porous media, within the framework of the major current issue on carbon dioxide capture and storage (CCS). Our project intends to simulate CO2 flow in porous media using the Lattice Boltzmann Model (LBM). The LBM is a discrete computational method based upon the Boltzmann equation. It considers a fundamental volume of fluid to be composed of a collection of particles. Each set of particles contained in these volumes is represented by a particle velocity distribution function for each fluid component at each grid point. During the time-step advance of the simulation, the fluid particles can collide with each other as they move, possibly under applied forces. The rules governing the collisions, such as Bhatnagar-Gross-Krook (BGK) are designed such that the time-averaged motion of the particles is consistent with the Navier-Stokes equation (Chen and Doolen 1998).

LBM is a mesoscopic method which is able to capture microscopic effects and reproduces macroscopic behavior of fluids as a result (Huang et al. 2014).

The aim of the 3+3 year project is to thoroughly investigate the LBM ability to handle multiphase multicomponent (specifically CO2-brine system) flows in porous media, using current state-of-the-art multiphase models and envision potential improvements in treating the interface such that the model can better accommodate the specific application.

In the presentation, Professor will give an overview of LBM and its mathematical-physical characteristics, as well as some examples of the progress of my research team in using LBM for multiphase flow modeling in meso-scale domains, in our progressive approximation to the more realistic conditions as those found in aquifers where CO2 is typically targeted to be stored.

Abstract:

This PhD thesis presents novel system control methods that can be utilized for effective and reliable operation of electric grids and passenger elevators. First of all, this study introduces a new spinning reserve allocation optimization technique that takes into account load and renewable power generation, inter-zonal conventional power generating capacity and demand response. Using the bivariate Farlie-Gumbel-Morgenstern probability density function, the framework presented in this thesis utilizes a new method to simulate the power generation of wind farms. In addition, the presented framework uses a Bayesian Network (BN) algorithm to fine-tune the spinning reserve allocation based on previous hours’ actual unit commitment, as well as the hour and day types.

The model proposed in this study has been tested on the IEEE Two-Area Reliability Test System (RTS) to quantify the effect of the bivariate wind prediction model and the Bayesian network-based Reserve Allocation Adjustment Algorithm (RAAA) on reliability and cost-effectiveness of the power grid. The findings show that combining a bivariate wind forecast model with RAAA improves power grid stability by 2.66 percent while lowering overall system running costs by 1.12 percent.

Secondly, the present work introduces an algorithm with an objective of optimal dispatching control of passenger lifts. The algorithm utilizes the data received from video cameras and dispatches the elevator cars based on the passenger count. The proposed algorithm utilizes the information on the number of people and dispatches the lifts with an objective to move the maximum number of passengers to the desired building levels within the minimum amount of time. In addition, the algorithm considers each person’s size and whether or not they have luggage. To account for uncertainty in image acquisition, the algorithm assigns the probability weights to the number of people who are waiting for a lift and riding the lifts. The main purpose of the algorithm is to minimize the following performance metrics: average travel time (ATT), average journey time (AJT) and average waiting time (AWT).

The suggested algorithm works well in situations of limited traffic sizes, according to a test case scenario conducted on a ten-story office building having four elevator cars (less than 200 people). In a scenario with large up-peak high intensity traffic, the proposed algorithm primarily underperforms. The proposed algorithm’s best output was seen in situations with random inter-floor passenger movement. In scenarios of changing traffic intensity and size ATT increased by 39.94 percent and 19.53 percent, respectively.
