Abstract

Their advantages are the ability to reduce or postpone the need for investment in the transmission and network. Their advantages are the ability to reduce or postpone the need for investment in the transmission and network. Their advantages are the ability to reduce or postpone the need for investment in the transmission and network. Their advantages are the ability to reduce or postpone the need for investment in the transmission and distribution infrastructure when optimally located; the ability to reduce technical losses within the transmission distribution infrastructure when optimally located; the ability to reduce technical losses within the transmission distribution infrastructure when optimally located; the ability to reduce technical losses within the transmission distribution infrastructure when optimally located; the ability to reduce technical losses within the transmission and distribution networks as well as general improvement in power quality and system reliability. and distribution networks as well as general improvement in power quality and system reliability. and distribution networks as well as general improvement in power quality and system reliability. and distribution networks as well as general improvement in power quality and system reliability.

Work specification for the construction of 33kv overhead lines across a lagoon using equal level dead-end lattice tower supports

“…Hence, marginal cost of Transmission or Distribution expansion is achieved [14]. Also, commissioning of such substation will have impact on sub-grid allocated distributable generation capacity or allocated parts of generation capacity [15]. Furthermore, the approximate total weight of the specified dead-end Tower estimated to be 538.2kg per tower, is a value that determines the expected calculated weight of Tower foundation by structural Engineers.…”

Impacts of Embedded Generation on Distribution Network Behavior

“…When SFCL is installed at the secondary side of main transformer or at the starting point of each feeder, total Impedance (denominator of (1)) is larger because of addition of impedance of SFCL in (1) and voltage sag duration is changed as the reduction of fault current.…”

“…Embedded Generation (EG) is a small scale electricity generation nearby end-users, ranges from 10KW to 10 MW, is directly connected to distribution network (DN).penetration of EG influence the distribution system (DS) operation [1] and though the intention of EG integration in to DS are to provide sustain voltage support [2], reactive power compensation [2], reduction of losses and reliability [3], [4]. EG integration shows immense impact on grid operation [5], voltage profile [6]- [8], power quality [9], [10], grid losses [11], fault current level [12], and existing protection system [13]- [17].…”

Optimal Location of Distributed Generation on the Nigerian Power System

“…IV. Place the DG at the corresponding position with optimum size and calculate real power losses using equation (1). V. Add the injection from DG for that bus and use base case values for state variables.…”

“…It has been stated in [1] that Distributed Generators (DG) are generators that are connected to the distribution network. They have the ability to reduce or postpone the need for investment in the transmission and distribution infrastructure when optimally located; the ability to reduce technical losses within the distribution networks as well as general improvement in power quality and system reliability.…”
