Battery energy storage technology for power systems—An overview

The penetration of renewable sources (particularly wind power) in to the power system network has been increasing in the recent years. As a result of this, there have been serious concerns over reliable and satisfactory operation of the power systems. One of the solutions being proposed to improve the reliability and performance of these systems is to integrate energy storage devices into the power system network. Further, in the present deregulated markets these storage devices could also be used to increase the profit margins of wind farm owners and even provide arbitrage. This paper discusses the present status of battery energy storage technology and methods of assessing their economic viability and impact on power system operation. Further, a discussion on the role of battery storage systems of electric hybrid vehicles in power system storage technologies had been made. Finally, the paper suggests a likely future outlook for the battery technologies and the electric hybrid vehicles in the context of power system applications.     

An economic analysis model for the energy storage system applied to a distribution substation

Recent developments and advances in energy storage technologies are making the application of energy storage technologies a viable solution to power applications. The energy storage system can store energy previously, and then release it in the proper time. Due to their flexibility, it is suitable to apply this technology to deregulated power markets. Therefore, this paper will build the economic analysis model for the energy storage system to apply to a distribution substation in a deregulated power market. The costs including installing energy storage system and operation and maintenance expense, and the revenues containing energy price arbitrage, reducing transmission access cost, and deferring facility investment are considered in this model. All these factors are evaluated by present worth value. Due to complexity of this problem, this paper proposes a method combining the genetic algorithm with linear program (GALP) to determine the optimal capacity and operations of the energy storage system.     

燃煤电厂碳捕集、利用与封存技术和可再生能源储能技术的平准化度电成本比较

作为同样可调可控的稳定低碳电源,燃煤电厂碳捕集、利用与封存（CCUS）与可再生能源储能技术的成本竞争性值得进一步探究。本文利用学习曲线模型比较了二者平准化度电成本（CLCOE）在2020—2030年间的竞争性变化,也进一步厘清了弃风弃光省份中二者的CLCOE水平。结果表明:目前,燃煤电厂CCUS较可再生能源储能系统具有竞争优势,如果燃煤电厂CCUS难以得到快速发展,到2028年,将丧失与可再生能源储能竞争的可能;到2030年,燃煤电厂CCUS平价上网的碳价需求水平为136~189元/t,但就目前的碳价发展趋势而言,通过碳收益实现平价上网存在难度;在弃光省份,燃煤电厂CCUS可通过调整发电小时数扩大与光伏储能技术的竞争优势;在绝大多数弃风省份,如河北、山西、内蒙、辽宁、吉林、黑龙江、贵州、陕西、宁夏、甘肃和新疆,其燃煤电厂CCUS在现有条件下较风电储能具有绝对的CLCOE优势。

Seeking energy equity through energy storage

Numerous states have adopted legislation and policy measures aimed at achieving greater equity across essential energy services on which underserved communities rely to meet basic needs. Equity is highlighted in the Biden-Harris January 2021 Executive Order No. 13,985, “Advancing Racial Equity and Support for Underserved Communities” (Exec. Order (2021)). When applied to the energy & utilities sector, ”energy equity” refers to the condition in which energy is provided to all in a consistent and systematically fair, just, and impartial manner regardless of race, geography, social standing, or economic position.Following this definition, energy equity is fundamental to healthy and prosperous social and economic systems, and contributes to regional and national security and stability. Data show that underserved populations generally suffer disproportionately from power outages, high energy prices, and polluting energy generation facilities. Numerous policy measures that include energy storage (i.e., residential, commercial, and utility scale batteries, and other technologies) can help provide energy equity to all populations. These policy measures address procurement mandates, replacement of peaker units, financial incentives, ownership policies and community projects, integrated resource planning and pilot programs, resilience, and long duration energy storage.     

Applications of shared economy in smart grids: Shared energy storage and transactive energy

Increasing renewable energy is integrated with power systems and more flexibility is required to address the fluctuation problems caused by renewable energy. Advanced communication and measurement technologies enable the electric grids to approach smart grids which have more solutions for the high penetration of renewable energy. The shared economy as an emerging commercial model has attracted much attention and is widely applied in smart grids. This paper is focused on the state of the art of shared energy storage and transactive energy (TE) which are the typical applications of shared economy in smart grids. The concept, market structure, and demonstration projects of shared energy storage and TE are provided.
