Über dieses Buch

Dieses Open-Access-Buch ist eine kohärente und zugängliche Wissensquelle über Flexibilitätsdienstleistungen im Energiebereich. Lokale Flexibilitätsdienste sind ein kommerzieller Mechanismus, der es den Teilnehmern ermöglicht, in Echtzeit oder als Reaktion auf vorherige Anfrage der Verteilnetzbetreiber (DSOs) eine Änderung ihres gewöhnlichen Stromverbrauchs vorzunehmen, um bei der Bewältigung von Netzüberlastung zu helfen. Das Buch fasst die wichtigsten Ergebnisse des Open Networks Programme der Energy Networks Association (ENA) zusammen und zeichnet die Entwicklung lokaler Flexibilitätsmärkte von "Proof of Concept" zu "Business as Usual" nach. Das Buch präsentiert detaillierte technische und organisatorische Erkenntnisse aus der Entwicklung lokaler Flexibilitätsmärkte, wobei der Schwerpunkt auf Gründung, Standardisierung, Vereinfachung und Transparenz bei der Entscheidungsfindung zwischen GB-Übertragungsnetzbetreibern und Interaktionen mit dem nationalen Energiesystembetreiber (NESO) liegt. Die Leser werden wertvolle Vergleiche der Umsetzungsansätze verschiedener Netzwerkunternehmen finden, die technische Nuancen und bewährte Vorgehensweisen hervorheben. Dieses Buch ist ideal für Forscher, Energieexperten und politische Entscheidungsträger und stellt eine wichtige Ressource zum Verständnis der Komplexität und Möglichkeiten von Flexibilitätsdienstleistungen in Energiesystemen dar. Egal, ob Sie im Energiemanagement, in der Politikentwicklung oder in der akademischen Forschung tätig sind, dieses Buch bietet wichtige Einblicke in die Zukunft der Energieflexibilität und des Netzmanagements.

    2. Chapter 1. Need for Distribution System Operation

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      The energy industry is changing. In response to the need to decarbonise our energy usage, new decentralised forms of electricity generation have evolved, supported by smart grid technologies. These technologies are also changing the way we use electricity, leading both residential and business users to become increasingly active in their energy usage. The challenges of decarbonisation, decentralisation and digitisation have the potential to create whole system opportunities by transforming the way distribution networks behave and creating new flexibility market opportunities for potential service providers. These markets will enable Flexibility Services to compete alongside traditional investment options for all relevant network reinforcements or upgrades of significant value, and to make the most cost-effective investment decisions in the future. This chapter describes the need for Distribution System Operation to harness these changes and ensure the efficient and secure transition of the local energy systems to meet net zero.

    3. Chapter 2. Market Principles

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      Increased volumes of embedded generation and smart, flexible demands provide consumers with more control and choice over how Britain’s homes, businesses and communities use their electricity and facilitate new competitive opportunities for participation in energy markets. Distribution system operators are facilitators of such markets and this chapter considers the market principles adopted by DSOs in developing GB markets.

    2. Chapter 3. Flexibility Products

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      A range of flexibility products has been developed by GB DSOs to meet different distribution system needs. These ‘products’ are set out as contracted services, generating monetary value for flexibility providers. This chapter explains more about these products and how they have been derived. This includes the key differentiators of flexibility products such as intended utilisation condition and notice period.

    3. Chapter 4. Forecasting and Development Plans (Pre-procurement)

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      Distribution System Operators (DSOs) need robust processes to forecasts future demand on their networks and from this future system needs. This chapter describes how GB DSOs have come together to develop consistent approaches to these functions through their Distribution Future Energy/Electricity Scenarios (DFES) Network Development Plans (NDP) that detail their network’s future needs for the next 10 years.

    2. Chapter 8. Interoperability of Flexibility Dispatch Systems

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      Interoperability of Flexibility Systems refers to the idea that the process and experience for an Flexibility Service Provider (FSP) being dispatched will be the same, irrespective of which network operator they are providing services to. This has been a significant area of focus for the Open Networks projects over the later stages of its work. This chapter provides an overview and insight into how interoperability of flexibility dispatch systems is being developed in GB.

    4. Chapter 10. Conflict Management (Primacy Rules)

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      Until relatively recently, the National Energy System Operator (NESO) and Distribution System Operator (DSO) performed distinct, and largely independent roles. Both organisations could consider the other's networks as being constraint free and having ready ability to access DER for their own needs. Increasing volumes of services from DER for both transmission and distribution system needs mean that the need for co-ordination between system operators is becoming increasingly imperative. This chapter considers how the underpinning rules around conflict management have been determined and the need for continued development of primacy rules.

    5. Chapter 11. Stackability of Flexibility Services

      • Open Access
      Avinash Aithal, Andrew Wainwright, Steve Atkins
      Abstract
      Operators of flexible assets seeking to maximise value from their assets have numerous options for their trading strategy. Sources of revenue include trading energy on the wholesale market; providing balancing services to the National Energy System Operator (NESO); capitalising on opportunities created by imbalance pricing; and more recently providing Flexibility Services to the Distribution System Operators (DSOs). Each revenue stream comes with associated commercial and regulatory complexity, and almost all of them are subject to ongoing development. Flexibility Service providers need to ensure areas of complexity do not inhibit their ability to provide services into different markets and potentially stack revenue opportunities. In response, it is incumbent on the DSO market facilitators to ensure arrangements are developed that minimise any friction between markets and allow as much participation as possible.
