Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Power-balanced instruction scheduling for Very Long Instruction Word (VLIW) processors is an optimization problem which requires a good instruction-level power model for the target processor. Conventionally, these power models are deterministic. However, in reality, there will always be some degree of imprecision involved. For power critical applications, it is desirable to find an optimal sche...

As an efficient alternative to fossil fuels, renewable energy sources have attained great attention due to their sustainable, cost-effective, and environmentally friendly characteristic. However, as a deficiency, renewable energy sources have low reliability because of their non-deterministic and stochastic generation pattern. The use of hybrid renewable generation systems along with the storag...

In order to improve the energy-saving level of commercial buildings? air-conditioning units with double cold sources and reduce energy cost, an optimal control method based on self-organizing neural network is proposed. Constrained parameter model double-cold-source constructed. Taking balanced real-time dynamic adjustment characteristic quantity inverter as object, combined fuzzy constraint va...

This paper presents a hierarchical control strategy for heat and electric power control of a building integrating hybrid renewable power sources including photovoltaic, fuel cell and battery energy storage with Plug-in Electric Vehicles (PEV) in smart distribution systems. Because of the controllability of fuel cell power, this power sources plays the main role for providing heat and electric p...

Power control is essential in the design of direct-sequence code-division multiple-access (DS-CDMA) techniques. Optimum power-control (OPC) methods with carrier-to-interference ratio (CIR) balancing have been formulated as eigenvalue problems for frequency-division/time-division multiple-access (FDMA/TDMA) cellular systems. For the CDMA cellular system, its OPC was also formulated as an eigenva...

small-scale dairy farming in bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

Development of distributed generations’ technology, trends in the use of these sources to improve some of the problems such as high losses, low reliability, low power quality and high costs in distributed networks. Choose the correct location to install and proper capacity of these sources, such as important things that must be considered in their use. Since distribution networks are actu...

More and more renewable sources are integrated into electric power grids worldwide. Their high generation dynamics, however, require power grid operators to monitor electricity generation and demand at a fine temporal resolution. Even small mismatches between supply and demand can impact the power grid’s stability, and thus ultimately lead to blackouts. As a result, smart metering equipment has...
