| description | Distribution system losses reduction has grossly been neglected by most electricity utilities although it contribute to no less than fifty percent [75% according to [1] } of total system losses. In contrast, loss minimisation during generation and transmission of electrical power has been well taken care of, using well developed methods such as economic despatch and unit commitment. The main objectives of this thesis is to look into new possible methods of distribution optimisation without incurring any addditional cost or extensive changing of existing equipmenmt or at minimum cost to reduce technical losses, reduce downtime and improve reliability. A new method called "Distribution Network Loss Minimization Using Islanding Technique" was inteoduced to fulfil the above objectives. This method takes into consideration thenexisting distribution network used in third world/ developing countries like in Malaysia. Unlike most other optimization methods which looks at the hardware of the system to reduce losses, this method is based on operational methodologies. The results shows that no hardware change was required to reduce losses as was shown in the case study. Nevertheless switchgears of the Ring Main Unit type will have to be changed to Vacuum Circuit Breakers and the existing IDMTL Oversurrent and Earthfaultprotective relays to direcational multi-characteristics numerical type should if further downtime losses and reliability is to be further improves. |
