  • Electric vehicles and the Electric grid a review of modeling approaches impacts and renewable energy integration
    Renewable & Sustainable Energy Reviews, 2013
    Co-Authors: David B Richardson
    Abstract:

    Electric vehicles (EVs) and renewable energy sources offer the potential to substantially decrease carbon emissions from both the transportation and power generation sectors of the economy. Mass adoption of EVs will have a number of impacts and benefits, including the ability to assist in the integration of renewable energy into existing Electric Grids. This paper reviews the current literature on EVs, the Electric grid, and renewable energy integration. Key methods and assumptions of the literature are discussed. The economic, environmental and grid impacts of EVs are reviewed. Numerous studies assessing the ability of EVs to integrate renewable energy sources are assessed; the literature indicates that EVs can significantly reduce the amount of excess renewable energy produced in an Electric system. Studies on wind–EV interaction are much more detailed than those on solar photovoltaics (PV) and EVs. The paper concludes with recommendations for future research.

  • data driven decision making in power systems with probabilistic guarantees theory and applications of chance constrained optimization
    Annual Reviews in Control, 2019
    Co-Authors: Xinbo Geng
    Abstract:

    Abstract Uncertainties from deepening penetration of renewable energy resources have posed critical challenges to the secure and reliable operations of future Electric Grids. Among various approaches for decision making in uncertain environments, this paper focuses on chance-constrained optimization, which provides explicit probabilistic guarantees on the feasibility of optimal solutions. Although quite a few methods have been proposed to solve chance-constrained optimization problems, there is a lack of comprehensive review and comparative analysis of the proposed methods. We first review three categories of existing methods to chance-constrained optimization: (1) scenario approach; (2) sample average approximation; and (3) robust optimization based methods. Data-driven methods, which are not constrained by any particular distributions of the underlying uncertainties, are of particular interest. Key results of the analytical reformulation approach for specific distributions are briefly discussed. We then provide a comprehensive review on the applications of chance-constrained optimization in power systems. Finally, this paper provides a critical comparison of existing methods based on numerical simulations, which are conducted on standard power system test cases.

  • energy and cost analysis of an air cycle used as prime mover of a thermal Electricity storage
    Journal of energy storage, 2018
    Co-Authors: Alberto Benato, Anna Stoppato
    Abstract:

    Abstract The increment of greenhouse gas emissions from human activities have forced the world authorities to ratify stringent environmental protection measurements devoted to the reduction of primary energy consumption and to the spread of Renewable Energy Sources (RES). To reach the fixed targets, governments have established subsidies especially to support the Electricity generation from RES like wind and solar. However, the large penetration of variable and intermittent RES is stressing the need of large-scale energy storage able to stabilize the Electric Grids. But, available large-scale energy storage technologies like Pumped Hydro, Compressed Air Energy Storage or Flow Batteries, suffer of geographical constrains, require fossil fuel streams or are characterized by low cycle life. For this reason, in the present paper, a new Thermal Electricity Storage configuration based on the Air Bottoming Cycle (ABC) concept is proposed and tested. The off-peak power is firstly converted into thermal energy using an Electric heater and, then, stored in a high temperature sensible heat storage. When the power demand is high, using a modified ABC the thermal energy is converted back into Electricity. Using the plant mathematical model, an energy and a cost analyses are carried out to estimate the performance and the system feasibility.

  • Selecting and optimal sizing of hybridized energy storage systems for tidal energy integration into power grid
    Journal of Modern Power Systems and Clean Energy, 2019
    Co-Authors: Seifeddine Ben Elghali, Rachid Outbib, Mohamed Benbouzid
    Abstract:

    The high penetration of renewable energy systems with fluctuating power generation into the Electric Grids affects considerably the Electric power quality and supply reliability. Therefore, energy storage resources are used to deal with the challenges imposed by power variability and demand-supply balance. The main focus of this paper is to investigate the appropriate storage technologies and the capacity needed for a successful tidal power integration. Therefore, a simplified sizing method, integrating an energy management strategy, is proposed. This method allows the selection of the adequate storage technologies and determines the required least-cost storage capacity by considering their technological limits associated with different power dynamics. The optimal solutions given by the multi-objective evolutionary algorithm are presented and analyzed.

  • A Holistic Approach to the Integration of Battery Energy Storage Systems in Island Electric Grids with High Wind Penetration
    IEEE Transactions on Sustainable Energy, 2016
    Co-Authors: Ismael Miranda, Nuno Silva, Helder Leite
    Abstract:

    This paper details an optimization tool for the planning and operation of battery energy storage systems (BESS) in island power systems with high wind penetration. The selection of the most suitable battery technology, its sizing and location is achieved through a comparative analysis of the operational and capital expenditure of the islanded system during the planning horizon with and without the deployment of the BESS solution. An operational algorithm is developed consisting on sequentially closer to time of delivery optimization stages in order to provide a robust quantification of the technical, environmental, and economic impacts of the battery system. The developed methodology is assessed and validated in a real-world case study of a Portuguese island with a high share of wind generation. Results show that BESS enhances the flexibility of the islanded power system thus ensuring a higher accommodation of wind energy with significant economic benefits.
