Abstract

Contemporary power systems are associated with serious issues of faults on high voltage transmission lines. Instant isolation of fault is necessary to maintain the system stability. Protective relay utilizes current and voltage signals to detect, classify, and locate the fault in transmission line. This paper presents the application of Artificial Neural Network (ANN) for transmission line loss evaluation of a power transmission system. Active and reactive powers of generators and loads; as well as the magnitudes of voltages at voltage – controlled buses and load buses are chosen as inputs to the ANN. System losses are chosen as targets to the ANN. Training data are obtained by NR Load Flow Studies for different load levels and system topologies using Mi-power software.

Abstract

In this paper, a wind-photovoltaic hybrid power generation system model has been studied and simulated. A hybrid system is rewarding as a particular power generation system is not completely reliable and if any one of the methods fail, the other will be able to supply power. A microgrid formed through a congregation of loads and distributed generators, which is operated as only one controllable system. As an integrated energy dealing system, the microgrid can run in parallel with or without separation from the primary power grid. This concept introduces the scarcity of multiple reverse conversions in a separate DC or AC grid and also immediate connections to variable renewable DC and AC sources and loads to power system. The microgrid can be deliberated to meet their individual demands, such as enhancement of local reliability, minimization of feeder losses, local voltages profile support, highest efficiency through the use of waste heat, improvement of voltage sag and maintain continuous power supply. In the present time, the performance of this system is noticed in the grid-tied mode. The PV system, battery storage and wind turbine generator are implemented for the formation of microgrid, and control tools are implemented for the converters.

Abstract

In a country like Nigeria, which do not have sustainable generation of electricity for its daily use, diesel or petrol generators are used as an alternative, which are expensive and environment unfriendly, and need frequent or regular maintenance. Without reliable energy infrastructure and renewable energy sources, agricultural productivity suffers. . In this research, a multiplex energy dispatch management, viz. Hybrid Renewable Energy Systems (HRES) has been proposed to solve the problem of power crisis in the country with the case study of Twins Dairy Farm. Most farm sites contain a wealth of crop and animal waste, which are useful resources for biomass/biogas. Also, the roofs of buildings are suitable for installation of solar panels, and small wind turbines. The principal objective of this proposed study is the possibility of utilizing such resources present in farms to satisfy the energy needs of the agricultural community. A comprehensive network study was carried out with the utilization of biogas, solar photovoltaic panels, thermal energy from the sunshine, diesel, and battery systems. The intention has been to minimize the capital cost for HRES and the operating cost depends on the energy demand of the farm.

Abstract

The demand for electric power is rising due to industrialization and urbanized life style. Existing generation and transmission facilities are not capable to fulfil this demand. Power transmission lines are pushed to operate close to their thermal and stability limits. This compromises the system security. Building new lines is difficult due to environmental, economic and political reasons. Here FACTS devices provide the opportunity to improve the power flows and voltages thereby enhancing the system security. FACTS devices improve Available Transfer Capability (ATC). This paper focuses on Thyristor Controlled Series Capacitor (TCSC) FACTS device. TCSC changes the electrical length of existing line and transmits large amounts of power when needed. It is a combination of TCR in parallel with capacitor. TCR is a variable inductor which is controlled by firing angle. This paper focuses on extensive literature review on the work done on TCSC device based on different criteria.

Abstract

The modern and luxurious life styles with the increased automated machinery and devices have increased the demand for electrical energy. This has been one of the primary reasons to maintain prescribed standards in the field of electrical energy in terms of reliability, power quality, and stability of power system network. When such highly interconnected power system network experiences a disturbance like unbalances in load, frequencies, unnecessary tripping, or due to some external causes, it leads to unsynchronization with power grid effecting a massive damage to economy of the country. So it is important and necessary to have high secured power system. Even though Indian power system is well equipped, well designed with protection system, a massive power outage has been taken place in Mumbai in October 2020 leaving many areas affected. This paper describes a detailed study on Mumbai power outage 2020.
