    A conceptual overview: integration of bi-directional electric vehicle (ev) chargers for effective peak grid demand management in Sri Lanka
    (IEEE, 2023-12-09) Induranga, DKA; Tharaka, VPV; Perera, WMKG; Priyadarshana, HVV; Koswattage, KR; Abeysooriya, R; Adikariwattage, V; Hemachandra, K
    This paper presents an energy analysis of the integration of bi-directional electric vehicle (EV) chargers for managing peak grid demand in Sri Lanka. This study addresses the challenges posed by peak demand and the way to address these issues with EV technology. The concept of bi-directional EV chargers is introduced, allowing EVs to both consume and feed energy back into the grid. The researchers calculated the benefit of using vehicle-to-grid (V2G) feeding systems for the years 2030 and 2040 assuming that the number of EVs is 10% of the total number of motor cars in the country. This method can provide 25% of the energy requirement of the current peak demand in Sri Lanka. Furthermore, this paper provides valuable insights that can guide further research and development in this area, contributing to sustainable grid utilization and EV adoption.

    Development of a model of cyber space for simulate cyber security level and data transmission latency of the modern power system
    (2019) Hemapala, KTMU; Priyadarshana, HVV
    The integration of DERs into the transmission and distribution grid introduces new consequence for distributed network operators (DNOs). Although distribution network was considered as a static system without major control operations or reconfiguration requirements. For a smart grid, distribution network can be considered as a dynamic system due to DERs. Power routing is an emerging concept. Its main purpose is to make the distribution network more flexible which will help to solve the technical issues related to DERs. With the introduction of DERs, DNOs have faced many challenges. Communication is one of major challenges in DNO Technology. Nowadays most of the communication architectures are based on the Internet that creates major security issues with the system. Cybersecurity Enabled Communication Architecture is the most important concept for Power Routing. The main objective of this research was achieving a Cyber-security Enabled Communication Architecture for Power Routing. This study has developed an IPSec tunnel for the cyber-security enabled communication. The method is simulated, and results are produced that shows the effectiveness of the developed communication method. The study shows that the developed cyber-security enabled communication architecture for power routing based on IPSec tunnel performs well to hide the related information in the Wide Area Network.
