  • A game-theoretic approach to optimizing the scale of incorporating renewable sources of energy and electricity storing systems in a regional Electrical Grid
    Energy Systems, 2015
    Co-Authors: Alexander S. Belenky
    Abstract:

    The problem of developing a decision support system for estimating a) the scale of incorporating available renewable sources of energy (such as solar and wind energy) in a part of a country’s Electrical Grid (called a regional Electrical Grid further in this paper), and b) the scale of storing electricity in this (regional) Electrical Grid to make these renewable sources of electric power competitive with traditional power generators (such as fossil-fuel and nuclear ones) and to reduce the cost of acquiring electricity from all the electric power generating facilities in the Grid is considered. In the framework of this system, renewable sources of energy are viewed as electricity generating facilities under both existing and expected electricity prices, and the uncertainty of energy supply from them and the uncertainty of the Grid customer demand for electricity during every 24 h are taken into account. A mathematical model underlying the system allows one to study the interaction of all the Grid elements as a game with a finite (more than three) number of players on a polyhedron of connected player strategies (i.e., strategies that cannot be chosen by the players independently of each other) in a finite-dimensional space. It is shown that solving both parts of the problem under consideration is reducible to finding Nash equilibrium points in this game.

  • Finding an optimal strategy of incorporating renewable sources of energy and electricity storing systems in a regional Electrical Grid
    Energy Systems, 2015
    Co-Authors: Alexander S. Belenky
    Abstract:

    A game with a finite (more than three) number of players on a polyhedron of connected player strategies is studied. This game describes the interaction among (a) the base load power plant (the generator), (b) all the large customers of a regional Electrical Grid that receive electric energy from the generator, as well as from the available renewable sources of energy, both directly and via electricity storing facilities, and (c) the transmission company. An auxiliary three-person game on polyhedra of disjoint player strategies that is associated with the initial game is also considered. It is shown that an equilibrium point in the auxiliary game is an equilibrium point in the above game with connected player strategies. Verifiable necessary and sufficient conditions of an equilibrium in the auxiliary three-person game are proposed, and these conditions allow one to find equilibria in (the auxiliary) solvable game by solving three linear programming problems two of which form a dual pair.

  • renewable energy transmission through multiple routes in a mobile Electrical Grid
    IEEE PES Innovative Smart Grid Technologies Conference, 2014
    Co-Authors: Yixiong Tang, Yijie Hong, Yuzhe Shen, Ting Zhu, Qingquan Zhang, M Begovic
    Abstract:

    Vehicle-to-Grid (V2G) technology utilizes the stored energy in electric vehicle batteries to contribute electricity back to the Grid. The energy in batteries can move with electric vehicles (EVs). Combining V2G and the mobility of vehicles, EVs can provide a natural energy transmission architecture called mobile Electrical Grid. The main idea of this paper focuses on multiple energy transmission route in mobile Electrical Grid from solar energy sources to places as capacity of every energy route is limited. The features of energy route in mobile Electrical Grid are analyzed and a minimum cost flow algorithm is presented. Simulations using real-world transporting data in Manhattan. Simulations show that this method is efficient.

  • potential of domestically provided ancillary services to the Electrical Grid
    International Universities Power Engineering Conference, 2017
    Co-Authors: Joannes Laveyne, Brecht Zwaenepoel, Greet Van Eetvelde, Lieven Vandevelde
    Abstract:

    In this paper we explore some methods to offer ancillary services by domestic demand response on a low voltage Grid. These Grids are becoming more and more inundated with decentralized renewable energy production, often leading to congestion issues. We show how domestically provided ancillary services can mitigate these problems. While demand response is already becoming established on large-scale installations, integration on a residential level poses some challenges toward cost and ease of integration. We present a solution that is both economic and non-intrusive and apply it on domestic electric water heaters. A project are where these solutions will be tested and verified is presented.

  • ancillary services for the Electrical Grid by waste heat
    Applied Thermal Engineering, 2014
    Co-Authors: Brecht Zwaenepoel, Joke Vansteenbrugge, Tine L Vandoorn, Greet Van Eetvelde, Lieven Vandevelde
    Abstract:

    Abstract This paper proposes a method to provide ancillary services to the Electrical Grid with waste heat recovery. The thermal flexibility needed to provide variable Electrical output is provided by connecting the thermal source to a thermal Grid and a thermal storage unit. Large capacity low heat grade thermal storages are cheaper and more readily available than large capacity Electrical storage solutions, and hence thermal storage is preferable. In this paper, the dimensions of a low temperature thermal storage buffer to balance the variability of a wind- or solar plant is determined. It is calculated that a spherical storage tank of 25 m diameter and 90–130 °C would be sufficient to balance the unpredictability of a 100 MW plant of either solar- or wind energy.

  • the impact on the Electrical Grid of hydrogen production from alkaline electrolysers
    International Universities Power Engineering Conference, 2010
    Co-Authors: Mahdi Kiaee, David G. Infield, Andrew Crude, Tamunosaki Graham Douglas
    Abstract:

    In the next 50 years, it is possible that hydrogen could become widely used as a fuel for transport. The result of this change could increase energy security and reduce environmental impacts, such as CO 2 emissions. Hydrogen produced by electrolysers could be used in Fuel Cell Vehicles (FCVs) with no direct harmful emission. In this research a scenario involving the widespread availability of Hydrogen at UK fuel stations for the purpose of supplying all vehicles is investigated. Calculations have been carried out to find out how much Hydrogen is needed for road transportation in the UK to be met in this way. The electrolysers will be assumed to be able to follow supply, i.e. their electricity consumption can be adjusted to follow changes in renewable energy generation in the power system. In this way these new electrolyser loads can be used for demand side management, facilitating the introduction of high volumes of renewable energy generation (mainly wind energy) to the power system. The interaction between the electrolysers and the network is investigated through modelling using MATLAB software.
