簡介

在能源行業,擺脫化石燃料是必不可少的。波動幅度較大的可再生能源的增加,加大了供給側的波動,創造了新的電網負荷形態。全球正在實施積極的清潔能源和減排目標,以及分佈式能源 (DER) 的新市場法規。在交通和建築領域,曾經依賴化石燃料的終端應用正在推進電氣化,在能源領域,正在利用數字化的進步來改善運營。

因此,負載靈活性作為在能源領域實現零排放的寶貴電網資源而備受關注。隨著供應側轉向可再生能源,負載靈活性通過減輕電網負擔和持續可靠運行在維持電網穩定性方面發揮著重要作用。為了使負載靈活性發揮其全部潛力並平衡電網,需要在能源市場中準確評估負載靈活性。

本報告分析了負載靈活性在電網中的重要性及其準確定義、驅動負載靈活性資源需求的因素,以及如何利用負載靈活性資源作為電網資源。負荷靈活性價值的決定因素、準確評估電力市場負荷靈活性的必要性、負荷靈活性對傳統電力公司商業模式的影響,以及未來關鍵利益相關者面臨的挑戰,將一併發送。

The energy industry is undergoing a foundational and necessary transition away from fossil fuels. The growth of variable renewable energy sources has increased supply-side volatility resulting in new net load shapes. Jurisdictions around the world are implementing aggressive clean energy targets and emissions reductions goals along with new market regulations for distributed energy resources (DER). The transportation and buildings sectors are increasingly electrifying end uses that once relied on fossil fuels, and advancements in digitalization are being used in the energy sector to improve operations.

As a result, load flexibility has been exposed as a valuable grid resource in the path to achieving zero emissions in the energy sector. Load flexibility plays a critical role in maintaining grid stability by reducing strain on the grid and allowing for continued reliable operation as the supply-side landscape trends toward renewables. To ensure load flexibility reaches its true potential and the grid remains balanced, load flexibility must be accurately valued in energy markets. Accurate valuation of load flexibility is expected to lead to fair competition with traditional generation sources as well as innovation.

This ‘Guidehouse Insights report’ discusses the ongoing shift in the energy industry from fossil fuel sources to renewable sources, its impact on grid operations, and the ways in which load flexibility can address that impact. The report provides a formal definition for load flexibility and recommendations to key stakeholders for incorporating and valuing load flexibility in their portfolios.

KEY QUESTIONS ADDRESSED:

  • What is driving the need for load flexibility as a resource?
  • How can load flexibility be used as a grid resource?
  • What can be done to determine the value of load flexibility?
  • Why is it important to accurately value load flexibility in energy markets?
  • What effect does load flexibility have on traditional utility business models?
