Impact of distributed generation on power system: Case study Astrit BARDHI Myrteza BRANESHI Alfred PJETRI
In this paper we will study the impact of small hydropower plants (SHP’s) built in recent years in Albanian power system such as energy efficiency, improvement of voltage level and increase of capacity of transmission power lines and social impact.
Content • The status of power system in Albania • Impact of small hydropower plants on power system: case study • The state of regional power system before Tervol SHP • The state of regional power system after Tervol SHP • Progress of small hydropower plants development in Albania • Environmental and social impact of SHP’S • Conclusions
The status of power system in Albania • Over 90% of Albanian electricity is produced by hydro power plants • The structural scheme of power system in Albania is radial: power generation – transmission lines - distribution • Power quality, mainly insouth Albania, has low voltage levels at some nodes and significantly transmission power losses • The annual energy production by hydropower plants depend on climatic conditions

Impact of Small HPP’s in Power System After SHPs Before SHPs
Impact of Small HPP’s in Power System • The power produced by HPPs has the possibility to supply the consumers with increased power quality at a better level. • The HPPs reduce the power losses and increase the capacity of transmission lines. • The HPPs improved the efficiency of power system • The small hydropower plants provides better utilization and optimization of water sources at Fierza Lake and Drini Cascade. • HPPs have riarioty producinggreen energy, with minimal environmental impact and reduce CO2 in atmosphere. • Inncreased the transmission capacity of power lines
Progress of small hydropower development in Albania • In recent years in Albania, are installed many of small hydropower plants • Small hydropower plants are usually connected at distributed power system. • The small hydropower plants are with canal deviation • Many small hydropower plants are built by private investors
Conclusions • SHP’s impacts in power system by improving the power at a better level of quality for consumers. • SHP’s reduce the power losses and “increase” the capacity of transmission lines improving the power system efficiency. • SHP’s provides better utilization and optimization of water sources at Fierza Lake and Drini Cascade. • SHP’s green energy, with minimal environmental impact and reduce CO2 in atmosphere. • SHP’s have an economical impact in the region by employing local residents for service and maintenance
