Optimal capacitor allocation in power systems

Computers & Electrical Engineering, 1983
Abstract Static capacitors are installed at specific locations in large power systems for minimising power losses and to ensure quality of the supply system. It has been found that the number of units in each capacitor bank can be considerably reduced by suitable choice of transformer tap settings and generator voltage magnitudes, thereby reducing ...

Optimal Power Allocation for Cooperative Networks

2010 Second International Conference on Communication Software and Networks, 2010
In cellular network, the deployment of the relay station can bring spatial diversity to increase link capacity and improve communication performance. In this paper, we consider an optimal power allocation scheme for the source and the relay to minimize the bit error rate(BER) at the destination under the power and outage constraint in cooperative relay

Optimal ATC Allocation in Power Systems

2008 Joint International Conference on Power System Technology and IEEE Power India Conference, 2008
When there are transmission service requests for a specific sink/source pair in a transmission system, the ISO must allocate the ATC of that pair to the requests. Since the requests could have different types, tariffs and time frame, the allocation must be accomplished in a sound and fair manner that considers various aspects of the requests.

Optimal Power Allocation for Secure Multicarrier Relay Systems

IEEE Transactions on Signal Processing, 2011
We study the multi-carrier decode-and-forward relay communication system, where an eavesdropper exists. The source power and relay power are optimized over all subcarriers to maximize the sum secrecy rate under a total system power constraint. From the power allocation result, an optimal transmission strategy is determined among no transmission, direct

Power-Optimal Module Allocation and Binding

1999
A number of researches have addressed the problem of minimizing power dissipation during module allocation and binding [RJ94] [KC97], scheduling and allocation [MC95], register allocation and binding [RJ94] [CP95a] and trading area for lower power through pipelining or parallelization combined with voltage scaling [GOC94] [CPRR92], scheduling using ...

Power-Optimal Register Allocation and Binding

1999
In the context of low power behavioral synthesis, automatic techniques must be developed that minimize the switching activity on globally shared busses and register files, that select low power modules while satisfying the timing constraints, and that schedule operations to minimize the switching activity from one cycle step to next.

Capacity Optimizing Power Allocation in Interference Channels

AEU - International Journal of Electronics and Communications, 2009
Abstract The interference channel is an essential model in both wireline and wireless communication systems. This article addresses transmit power allocation in interference channels with total transmit power constraint. The optimum power allocation maximizing the sum rate in two user interference channels can be derived analytically.

On optimal power allocation for turbo codes

Proceedings of IEEE International Symposium on Information Theory, 2002
A scheme for optimum power allocation for the different bits of a turbo code is introduced. It is shown that by employing this scheme performance improvements in the range of 0.5-0.7 dB can be achieved without introducing any complexity or delay at the decoder.

Optimal power flow incorporating wind power and optimally allocated energy storage

Wind Engineering, 2019
The rapid growth of wind power poses new challenges for power system operators and electricity marketers. The benefits of using wind power are emission reduction and decrease in consumption of conventional resources. But the inherent nature of wind energy poses challenges in the power system operation and planning.

Optimizing MBMS Power Allocation through HSDPA Transmissions

2009 Fifth Advanced International Conference on Telecommunications, 2009
Multimedia Broadcast Multicast Service (MBMS) epitomizes the increasing popularity of enhanced end-user experience in Universal Mobile Telecommunications System (UMTS), since it allows the economical delivery of multimedia services to a large number of users. MBMS multicast supports both Point-to-Point (PTP) and Point-to-Multipoint (PTM) modes in order
