Just released: Transmission Expansion Planning Model Considering Battery Energy Storage, TCSC and Lines Using AC OPF

Flexibility has become a requirement for modern power systems dominated by renewable generation sources. It can be extracted from different assets, ranging from demand response to fast generating units. This paper proposes an investment model that nds an optimal mix of transmission-level non-generation flexible assets: battery energy storage (BES), thyristor-controlled series compensators (TCSC), and transmission lines. The role of BES is to offset renewable generation in time, but its power converter is additionally utilized to provide voltage regulation by injecting/withdrawing reactive power.

TCSC is used to alter power flows and increase existing lines’ capacity, while new power lines are used to increase bulk power transfer. The proposed planning model uses a linearized AC OPF and employs Benders’ decomposition to develop an iterative procedure for obtaining the optimal solution. The presented case study illustrates the usefulness of the model for different BES costs and investment policies.

WORKSHOP | H2020 Low TRL Smart Grids and Storage Projects Clustering

Workshop | 3rd December 2020 | 12:20 (CET)

André Guimarães Madureira (INESC TEC), Tomislav Capuder (ICENT), Florin Capitanescu (LIST), Eduardo Alejandro Martínez Ceseña (UNIMAN), and Martin Bolfek (HEP ODS) will present ATTEST in a workshop with other European projects of the energy field.

The event is organized by the European Commission and will approach seven different sub-clusters:

  1. Business models
  2. Novel energy storage
  3. Sector coupling
  4. Data management & interoperability
  5. Ancillary services at distribution grid level
  6. New compatible architectures for the grid
  7. Flexibility assessment and modelling, including probabilistic services

Registrations will soon be open. Stay tuned!
