A distributed generation is a small-scale Installed in the customer density sources. The benefits of distributed energy resources is one example. To improve the reliability of power distribution system for the better. The increased reliability of power distribution system that is connected to the source of power distribution efficiency depends on the size of the supply and installation of power distribution are considered appropriate. To Evaluation the reliability in distribution system with the main purpose is to the minimization for customer interruption cost. The technique employed to minimization problem for customer interruption cost in solved by the developed tabu search algorithm together with reliability worth analysis that provide an indirect measure for cost implication associated with power failure. The developed methodology is tested with a distribution system of Roy Billinton Test System (RBTS) bus 2. Numerical results from the tests demonstrate that distributed generation can be used to promote economy and reliability of the distribution systems.

Research this project invents for design and build the water turbine produce the electricity by set up the equipment produces the electric current from water energy flows from the nature which be new choice for Thailand in using energy pays back. then born the idea in energy water lead flows in the tide comes to use is born the advantage The water turbine has produced the electricity that does designing and establish to compose 3 part importance be the part of water buoy water turbine part is the pin wheel that is made of the iron each have a draught 30-40 centimeter group part carries round which compose the gearwheel yes carry round and a transmitting belt carry round . From pin wheel test produces the electric current that establishes to induce float in a river already record seek feeling numb fire efficiency reaches to open 220 AC notgood but 12 DC good and use inverter to 220 v.
