    Share of Non-Conventional Renewable Energy (NCRE), small hydro, wind, solar, bio-mass etc based electricity generation in Sri Lanka at present is 10% of the total annual generation. The Government of Sri Lanka has declared a national target of 20% from NCRE by 2020[1]. Most of NCRE power plants have been connected to the distribution network and are termed as Distributed Generators (DGs). With the increase of share of DGs, it affects system reliability, power quality and economic operation of the distribution network. This paper focuses on the impact of economic operation of transmission and distribution network due to distributed generation in Sri Lankan power system. Network simulation studies have been carried out for transmission network and for four grid substations to which many DGs have been connected. The analysis revealed that transmission network losses have reduced with increase penetration of DGs to the system while distribution network losses are dependent on the amount of DG capacities connected to the distribution network. However, there is a reduction of network losses when overall network is considered thereby giving financial benefit from DGs added to the system.

    Techno-economic feasibility of using 400 kV for the 2032 transmission system of Sri Lanka
    (Institute of Electrical and Electronics Engineers, Inc., 2016-12) Alahendra, GB; Banda, HMW; Lidula, NWA; Rajapakse, A; Prasad, WD
    Congestion occurs on the nation’s electric transmission grids with the addition of new generation to meet the increasing electricity demand. Therefore, reliable, efficient and better quality of supply urge introduction of new higher voltage levels for power transmission. However, it has to be technically feasible and economically justifiable for the country. Technical feasibility and economic justification of introducing a higher voltage than that of existing voltage to transmit bulk power to load centers from bulk power generating stations in Sri Lanka is discussed in detail in this research.
