An E cient Power Control Mechanism in CellularCommunicationsD
نویسنده
چکیده
In this paper we study the maximum number of users that each base station can support on a path-loss channel. We analyzed the desired user's signal quality in a single cell CDMA (Code Division Multiple Access) system in the presence of MAI(Multiple Access Interference). Power control techniques attempt to assure that all signals are received with equal power levels. Since the algorithm is designed for a imperfect control of power, the capacity of the system is reduced for a given BER. An attempt has been made on the reverse link (mobile to base station) analysis assuming log-normal shadowing and Rayleigh fading 1]. The simulation works are presented in this paper and the numerical results show that the proposed method can satisfy the required quality of service for multimedia wireless LAN application.

Voltage Coordination of FACTS Devices in Power Systems Using RL-Based Multi-Agent Systems
This paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. In this study, some FACTS (flexible AC transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. Each device here is modeled as ...
متن کاملMarket and Resource Allocation Algorithms with Application to Energy Control
The energy markets of today are markets with rather few active participants. The participants are, with few exceptions, large producers and distributors. The market mechanisms that are used are constructed with this kind of a market situation in mind. With an automatic or semiautomatic approach, the market mechanism would be able to incorporate a larger number of participants. Smaller producers...

This paper develops an adaptive control method for controlling frequency and voltage of an islanded mini/micro grid (M/µG) using reinforcement learning method. Reinforcement learning (RL) is one of the branches of the machine learning, which is the main solution method of Markov decision process (MDPs). Among the several solution methods of RL, the Q-learning method is used for solving RL in th...
