This study investigates the potential of using transmission power control in wireless packet networks with differing number of hops between source and destination. Here we exploit the benefits of power control in the context of multi-hop wireless ad hoc type networks with a distributed media access control. For our investigations we choose several general ad hoc network topologies and studied t...

This paper presents a closed-loop control of an 800W fuel cell power system consisting of phosphoric acid fuel cell (PAFC), an ultracapacitor, power controlling unit and grid side filters. Simulation results represent the dynamics of the PAFC and its related power conditioning devices including grid connection. The proposed model is based on mathematical equations. The modeling and simulation i...

Since more distributed energy resources (DER) are being linked to the electrical grid, current power system (DPS) is encountering additional voltage regulation challenges. Traditionally, on-load tap changers, step regulators, and switched capacitor banks have been used for in DPS. However, these sources insufficient As a result, reactive assistance from DER unit based on electronics intended ad...

This paper aims to design an optimal distributed multi-agent controller for load frequency control and optimal power flow purposes. The controller parameters are optimized using Grey Wolf Optimization (GWO) algorithm. The designed optimal distributed controller is employed for load frequency control in the IEEE 30-bus test system with six generators. The controller of each generator is consider...

This paper deals with Enhanced Phase Locked Loop Control scheme for Distributed Static Compensator (DSTATCOM) in the distribution system. The proposed control scheme based DSTATCOM eliminates current harmonics, maintains unity power factor at source, zero voltage regulation and load balancing. The Enhanced Phase Locked Loop (EPLL) Control scheme is based on Digital Signal Processing (DSP) which...

Introducing distributed generation into a power system can lead to numerous benefits including technical, economic, environmental, etc. To attain these benefits, distributed generators with proper rating should be installed at suitable locations. Given the similar effects of distributed generators and capacitor banks on operation indices of a distribution system, simultaneous assignment of best...

Custom power is a technology driven product and service solution which embraces a family devices such as Dynamic Voltage Restorer (DVR), Distributed Shunt Compensator (DSTATCOM), Solid State Breaker (SSB) etc which will provide power quality functions at distribution voltages. The rapid response of these devices enables them to operate in real time, providing continuous and dynamic control of t...

The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...

There has been an increasing interest in recent years to deliver multimedia services over wireless ad hoc networks. Due to the existence of hidden terminal and absence of central control, the MAC protocol as used in the ad hoc networks may lead to channel capture, where some flows monopolize the channel while others suffer from starvation. This greatly degrades system throughput and fairness. A...
