This paper focuses on improving the active and reactive power control of Wind Energy Conversion System (WECS) by employing the Battery Energy Storage System (BESS) and controlling the frequency and voltage regulation instantaneously. The proposed power control scheme is composed of two control loops so that they are implemented and designed for active power control and controlling the reactive ...

Reactive power plays an important role in supporting real power transmission, maintaining system voltages within proper limits and overall system reliability. In this paper, the production cost of reactive power, cost of the system transmission loss, investment cost of capacitor banks and absolute value of total voltage deviation (TVD) are included into the objective function of the power flow ...

Spectrum scarcity is a major challenge in wireless communications systems requiring efficient usage and utilization. Cognitive radio network (CRN) is found as a promising technique to solve this problem of spectrum scarcity. It allows licensed and unlicensed users to share the same licensed spectrum band. Interference resulting from cognitive radios (CRs) has undesirable effects on quality of s...

In order to increase the available power of electrical energy distribution station and improve voltage profile lines, use shunt capacitor banks is indicated. The main results obtained during this study are: a reduction in subscribed from 14913.978 kVA 14010.100 kVA, transformer load rate 99.4% 93.4%, reactive called 5481.729 kVAr 481.729 kVAr, an active transported by substation 8505.062 kW 896...

this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...

The fundamental component of resource management in Wireless Sensor Network (WSN) is transmitter power control since the sensors are miniature battery powered devices. Power control is an important research trend in WSNs for improving the efficiency of network communication and prolonging the life time of the network thereby supporting system quality and efficiency. This paper analyses a game t...

In this thesis, we propose a framework for designing decentralized pricing and centralized auction mechanisms in the presence and absence of malicious users. First, we design pricing mechanism for efficient power allocation in the uplink of a single cell Multi Carrier Code Division Multiple Access (MC-CDMA) system with strategic and price taking users. The mechanism is extended to sum power con...

Smart home, which controls the end use of the power grid, has become a critical component in the smart grid infrastructure. In a smart home system, the advanced metering infrastructure (AMI) is used to connect smart meters with the power system and the communication system of a smart grid. The electricity pricing information is transmitted from the utility to the local community, and then broad...
