HEAPD is a diverse research consortium sponsored by EPSRC (EP/K036211/1) and the Indian Research Council (DST) to address the low carbon integration challenges through the adoption of local direct current (DC) electricity networks.

The research outputs from this project will provide foresight into the development of low-carbon smart grids to enhance the security of power supply in India and the UK.

The HEAPD consortium will take the timely step of investigating how DC power networks can increase the efficiency of renewable energy-storage systems deployed at a community level to benefit the resilience of the national power grid. The research outcomes will deliver cheaper and securer solutions to complement the traditional risk prevention techniques used by grid operators, anticipating the added risks of introducing low carbon, low-inertia, and low-availability generation technologies.

The main objectives of HEAPD Project will focus on five areas that have been identified as key to the integration of future DC power networks:

  • Model and characterise local DC grids in terms of their ability to provide demand reduction, demand shifting and demand security, and quantify their benefits in terms of reduction in local and wider system operation costs, improvement in local voltage profiles and in supply reliability for local and wider systems.
  • Develop an ultra-fast simulator that will reflect the impacts from local resources and identify large energy imbalance and security risks well ahead of time.
  • Investigate key drivers for large energy deficit in the current and future low-carbon systems. The risk investigation will be conducted between the UK and India supply systems, and between the current high carbon and future low carbon systems.
  • Investigate how to modulate local DC resources to insulate the system against security risks in a low carbon system, and quantify the benefits of extending the service of local DC grids to national security.
  • Investigate the required innovations in local DC grids’ technologies, tariff structures and social interventions to deliver the potential benefits and change the business case of local DC grids.
