In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

Over the last several decades, land-use/transport interaction models have evolved. Although these potential to become primary demographic forecasting and planning vehicles in metropolitan transportation for most large US urban regions, some gaps improvements must be addressed. This paper briefly discusses a newly developed refined integrated land-use/transportation model. It also introduces inn...

Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...

Generation expansion planning problems should take into account not only satisfaction of future demand but also environmental constraints, such as government imposed limits on pollution produced by coal based power plants. For a vertically integrated system of power plants, we model those features as a two-stage stochastic programming problem with recourse that can be solved by decomposition me...

The portfolio of virtual power plants (VPP) is a flexible system for facilitating wide range resources with geographical coverage. A VPP can be placed at the intersection electric and energy systems by adding heat pumps to portfolio, thereby accelerating formation integrated systems. VPPs, while virtual, still rely on physical network operations. transmission has responsibility ensuring securit...

in the past few decades, increasing growth of wind power plants causes different problems for the power quality in the grid. normal and transient impacts of these units on the power grid clearly indicate the need to improve the quality of the electricity generated by them in the design of such systems. improving the efficiency of the large-scale wind system is dependent on the control parameter...

Aggregate production planning (APP) is one of the most important issues carried out in manufacturing environments which seeks efficient planning, scheduling and coordination of all production activities that optimizes the company's objectives. In this paper, we develop a mixed integer linear programming (MILP) model for an integrated aggregate production planning system with closed loop supply ...

Abstract With the continuous expansion of scale renewable energy generation and rapid development its technology, forms power grid become more diverse. Meanwhile, coupling uncertainty various heterogeneous resources will significantly change characteristics dynamic balance mechanism system. Power generated from sources such as wind light is uncertain uncontrollable, enjoys complementary across ...
