  • Review of distribution network phase unbalance: Scale, causes, consequences, solutions, and future research directions

    Abstract

      

    Phase unbalance is widespread in the distribution networks in the UK, continental Europe, US, China, and other countries and regions. This paper first reviews the mass scale of phase unbalance and its causes and consequences. Three challenges arise from phase rebalancing: the scalability, data scarcity, and adaptability (towards changing unbalance over time). Solutions to address the challenges ar...

  • Implications of COVID-19 for the electricity industry: A comprehensive review

    Abstract

      

    As COVID-19 sweeps through the whole world, human activities have been changed significantly. Under such circumstances, the electricity sector is deeply affected and faced with great challenges. This paper provides a comprehensive review of the impacts that the pandemic has caused on the electricity sector. Electricity demand has dropped sharply as governments around the world executed lockdown re...

  • Review of charge accumulation on spacers of gas insulated equipment at DC stress

    Abstract

      

    Charge accumulation on the spacer surface in gas insulated equipment is very severe in the DC field, leading to easy flashover, which restricts the application of DC GIS/GIL. Therefore, knowledge about the charge accumulation characteristics of gas insulated equipment at DC stress is essential. In this paper, we reviewed the research methods and the characteristics of charge accumulation on spacer...

  • Testbeds for integrated transmission and distribution networks: Generation methodology and benchmarks

    Abstract

      

    For future power systems with high penetration of distributed energy resources (DER), the coordination of the transmission system (TS) and distribution system (DS) is quite essential. In this paper, multiple testbeds that consist of various sizes of TS and DS models are designed for power flow (PF) and optimal power flow (OPF) analysis of the integrated transmission and distribution (T&D) systems....

  • Real-time dispatchable region of renewable generation constrained by reactive power and voltage profiles in AC power networks

    Abstract

      

    A large amount of renewable energy generation (REG) has been integrated into power systems, challenging the operational security of power networks. In a real-time dispatch, system operators need to estimate the ability of the power network to accommodate REG with a limited reserve capacity. The real-time dispatchable region (RTDR) is defined as the largest range of a power injection that the power...
