Series capacitors increase the power transfer limit of transmission lines. However, the protection of series compensated lines using only local measurement is challenging. Phasor based distance protection experiences delay and directional problems in the presence of a series capacitor. This paper presents an incremental quantity based distance prot...
Series capacitors are installed in transmission lines to increase power transfer capacity. However, their addition creates challenges for the line protection. Security and speed of phasor based protection schemes that work with local measurements (communication independent) are severely affected in the presence of series capacitors. Therefore, time...

The introduction of series capacitors in transmission lines causes problems in terms of reliability and the security of distance protection relays. As distance protection is widely used in the transmission network, the challenge of applying it to series compensated lines has been taken up by utilities and relay manufacturers in various ways. In the...
Introduction of series capacitors in transmission lines can cause problems with reliability and security of distance protection, due to problems such as current inversion, voltage inversion and sub-synchronous oscillation. Distance protection is widely used for transmission lines and has desirable features not available from traditional alternative...
In Bangladesh, despite available feedstock for producing biogas, the development of biogas production has been very slow. The objective of this research was to study the drivers for and barriers to biogas technology implementation in the country. As the research involved different types of stakeholders related to biogas production, the outcome prov...
Series compensation of transmission lines creates several challenges for distance protection, particularly at the high compensation levels that have recently become more common. In this paper, the effect of high levels of series compensation on distance protection is evaluated, using a PSCAD simulation model of a 500 kV, 200 km transmission line wi...

The uncertainty in solar energy is different from conventional, dispatchable generation fuels and difficult to incorporate into the standard system operating procedures. In the first part of this work, the machine learning algorithm is used to train models based on solar irradiance data and different meteorological weather information to predict th...
Series capacitors are used in transmission lines
for enhancing power transmission limit. However, they complicate
the line’s protection due to impedance change of the
line, voltage inversion, current inversion and sub-synchronous
oscillation. Distance and differential protections are used in
different arrangements in transmission line protection. O...
Series capacitors are used in some transmission lines
to raise the power transfer limit. If a fault occurs at a location
behind which the total reactance is capacitive, the result is
current inversion, also known as current reversal. In a current
inversion, current leads the voltage instead of lagging it. The
probability of current inversion increa...
This paper provides a technical analysis of energy harvesting (EH) in the field of power and energy sector, including different aspects of harvesting energy, individual case history, control strategies of harvesting in the field of power and energy sector together with the current trend and future aspects of it. EH is comparatively a new concept wh...
The aim of this paper was to study energy management and improved energy efficiency among large iron and steel mills in Bangladesh. The results show that there are some barriers to energy management practices among large steel mills, the most important barriers being the perceived absence of cost-effective technical measures, high perceived risks d...
One imperative challenge in building a sustainable
electricity future is to integrate renewable energy sources in the
present energy mix. Renewable energy sources are inherently
different in nature from their conventional counterparts. Thus
integration to existing system posses a substantial challenges. In
this paper using a IEEE 14 bus test system...
Hatiya Island in Bangladesh is an off grid remote locality. Despite being only twenty kilometers away from shore the island lacks any electricity grid connection. There has been governmental initiative for establishing a hybrid power plant in the island but that project was not realized. Thus there is a need for further investigation to plan electr...
Renewable energy can help the countries to meet their sustainable development goals. It provides provision of access to clean, secure, reliable and affordable energy. Renewable energy has gone mainstream, accounting for the majority of capacity additions in power generation today. Today wind power plant technologies are experiencing renaissance and...
This paper provides a technical analysis of energy harvesting, different aspects of harvesting energy, individual case history, control strategies of harvesting in each energy sector together with current trend and future aspects of it. Energy harvesting is comparatively a new concept which is growing very fast since 20th century and catching new g...
The uncertainty in solar energy is different from conventional, dispatchable generation fuels and can be difficult to incorporate into standard system operating procedures. We are moving towards a time where people will be generating energy by themselves from solar on their rooftops that would significantly increase utilities' solar share of energy...
p>It is known that the heat treatment process in the
production of extruded cables, affects the electrical
properties of polymeric insulation materials; this effect
is via two main phenomena; first, it leads to diffusion
and removal of polar substances from the system;
second, it affects the polymer morphology by increasing
the polymer chain relaxa...
Polyethylene is used extensively as an insulating material in high voltage power cables, it is therefore important to understand the behaviour of polyethylene under different conditions. This is a study regarding the relation of heat treatment and the effect of morphological changes on the dielectric properties of polyethylene samples. Polyethylene...
