AbstractDuring the distribution process there will be a loss of some of the energy that is channeled. This phenomenon is known as losses. This is caused by technical and non-technical factors. In the  State Electricity Service (PLN) system, distribution losses or energy losses is calculated by measuring the difference between kWh produced and kWh sell. This kWh difference is the electrical energy lost during the starting process from the generation or secondary side of the Substation to customers’ APP. Cumulatively, the amount of kWh at all base sources is 73,769.524 kWh while the distribution loss that occurs in JTM is 5,835.008 or 7.91%. One way to overcome and minimize distribution losses in the 20 kV Procurement Service Unit (ULP) of Lima Puluh distribution system is to analyze the distribution network system, add new feeders and break the load on the electrical system. The simple branch exchange method is used to separate the network load, which is done by adding a switch by turning the on or off channel and searching for the configuration that produces the smallest power loss and calculating the power loss based on the network load. Based on the simulation results using the ETAP 12.6 software, the results of the energy loss of Procurement Service Unit (ULP) of Lima Puluh is 5,864,112 kWh then decreased after load separation of 4,341,348 kWh. The value of power loss before load separation is 1,955 kW and a decrease in power loss after load separation is 1,484.5 kW. The investment cost incurred for the construction of a new feeder is RP. 22,000,000,000,- with a payback of 9.9 years.  Keywords: Feeder, Power Loss, Energy Loss, ETAP 12.6.

The main aim of the distribution system is delivery the power to the consumers. Because of, aging of electrical infrastructure, old control mechanism, increased power demand causing exploitation of the present electrical networks leads to low voltage profile, more active and reactive power loss with various power quality related issues causing poor network operation. In this method maximization of voltage profile with energy loss minimization is carried using network reconfiguration along with optimal siting of the distributed generation (DG). The proposed methodology is carried out on five bus system. The obtained results are impressive interms of voltage stability and power loss reduction.

Renewable energy-based distributed generators (DGs) are gaining more penetration in modern grids to meet the growing demand for electrical energy. The anticipated techno-economic benefits of these eco-friendly resources require their judicious and properly sized allocation in distribution networks (DNs). The preeminent objective of this research is to determine the sizing and optimal placing of DGs in the condensed DN of a smart city. The placing and sizing problem is modeled as an optimization problem to reduce the distribution loss without violating the technical constraints. The formulated model is solved for a radial distribution system with a non-uniformly distributed load utilizing the selective particle swarm optimization (SPSO) algorithm. The intended technique decreases the power loss and perfects the voltage profile at the system’s nodes. MATLAB is used for the simulation, and the obtained results are also validated by the Electrical Transient Analysis Program (ETAP). Results show that placing optimally sized DGs at optimal system nodes offers a considerable decline in power loss with an improved voltage profile at the network’s nodes. Distribution system operators can utilize the proposed technique to realize the reliable operation of overloaded urban networks.

This paper presents the optimal and sizing of distributed generation (DG) placement in a radial distribution system for loss reduction. The main emphasis of this paper is to identify proper locations for installing DGs in a distribution system to reduce active power loss and improve bus voltages. Nevertheless, proper placement and sizing of DG units are not straightforward to be identified as a number of their positions and capacities need to be determined. It is therefore proposed in this paper to solve a DG placement problem based on a Tabu search algorithm. The objective function of the problem is to minimize the system loss subject to power flow constraints, bus voltage limits, pre specified number of DGs, and their allowable total installed capacity, and only one distributed generator for one installation position. The effectiveness of the methodology is demonstrated by a practical sized distribution system consisting of 69 bus and 48 load points. The results show that the optimal DG placement and sizing can be identified to give the minimum power loss while respecting all the constraints.

The standard air density of 1.225 kg m−3 is often used in determining the energy output of a wind turbine although the energy output is dependent on a site's air density. By using measurements of temperature, dew-point temperature, and pressure, we calculate the monthly air density of moist tropical climates at two sites in the small-island state of Trinidad and Tobago. In addition, we calculate the energy output of a BOREAS 30 kW small wind turbine using the 10 m level wind speed distribution extrapolated to hub height. The average air densities at Crown Point and Piarco were 1.156 kg m−3 and 1.159 kg m−3, respectively, and monthly air densities at both sites were at most 6% less than standard air density. The difference in energy output of the BOREAS 30 kW calculated using standard air density over that using the local site's air density could provide electrical energy for the continuous monthly operation of 6 light bulbs rated at 50 W at Crown Point and 4 light bulbs at Piarco. Thus, communities interested in implementing wind turbine technologies must use the local air density of the site when sizing a wind turbine system for its needs.
