The industrialization and the growth of the population are the first factors for which the consumption of electrical energy increases regularly. As well, to have a balance between production and consumption, it is at first sight necessary to increase the number of power plants, lines, transformers etc[1], which implies an increase of the cost and a degradation of the natural environment. Accordingly, it is important today to have of mesh networks and work close to the limits of stability [2]-[5]. The exploitation of electrical networks requires to improve the management of energy by introducing the costs of production and minimizing the transmission losses. Scientific research is oriented toward the best form of economic distribution of electrical energy in order to minimize the costs of production [6]-[10]. For a good operation of the network, we need to solve the problems of a technical and economic, which requires the improvement of the management of electrical energy by reducing the cost of production and on the other hand by keeping the balance between production and consumption [11]. The current objective of an economic dispatch is the electrical production with a low cost of fuel. The general problem of the production and the optimal distribution of powers in a production system -Transport- consumption are therefore very complex. Several methods like PSO [12], bat algorithm [13], [14], Honey bee swarm [15]˗[18] league championship algorithm [19], [20], cuckoo search [21], simulated annealing [22], [23], krill herd optimization [24]-[29],Virus Optimization Algorithm [30]-[32], Magnetic Optimization Algorithms [21], [23], etc, have been developed to resolve this problem Here, a new meta-heuristic technique Egyptian Vulture Optimization [33], [34] is implemented to solve economic dispatch problems, and present its effectiveness using three, six, fifteen and forty generating units test systems. The result shows t[...]

Energy has served as an important source of economy for many decades. What is meant by energy? Energy is for instance, natural gas, diesel, coal, and electricity, this energy is needed to run vehicles, devices, machines: to fertilize and irrigate lands, harvest crops, to light up and heat apartments, buildings and factories. Since the use of energy is involved in each step of previous fields, surely people’s welfare is likely to go down in the lack of energy. [1]. Fossil fuels like coal, oil and natural gas are currently the world’s primary energy sources. The heavy dependence on the fossil fuel reduced the natural reserve of it. To take care of the balance and limited life of conventional sources which creates danger on the environment, research on alternative sources of energy is carried out [2]. In current decades, renewable energy resources have received considerable attention in both grid independent and on-grid applications. The benefits associated with renewable resources include: reducing environmental pollution, endlessness, improved power quality, and reliability, and saving power for the next generations [3, 4]. Engineers and scientists are increasingly trying to find and use alternative energy sources. The three most widely used renewable energy sources are hydro, wind and photovoltaic (PV) [5]. Fig.1. Most common forms of renewable energy A well-engineered renewable energy system can reduce costing of energy, consequently improving lifestyle [6]. Hybrid power system uses more than one type of generator, usually, a conventional generator powered by diesel, and a renewable energy source such as wind energy and photovoltaic (PV). Various “hybrid" system of renewable energy sources and diesel generators are currently being developed and marketed [7]. The present paper comprehensively reviews the hybridization of wind, PV energy and gas turbine, installed in Naama-Algeria. This study will analyze[...]

The development and use of clean renewable energy in many parts of the world in the last two decades have become vital due to the continuous decline and price fluctuation of fossil fuel resources and global concerns about climate change, air pollution and increased consumption of energy [1,2]. Advances in power electronics have also contributed more effectively and more reliably to the integration of renewable resources into power grids [3]. The cost reduction of photovoltaic (PV) technology and related components, such as inverters and batteries, and the sharp decline in the cost of large wind turbines have made these energy sources more attractive in many countries. The large-scale development of renewable energy systems and their integration to utility grid are considered as the most important challenges for the sustainable environment. The electric energy industry restructuring and the introduction of the concept of a smart grid have also led to new technologies (distributed energy resources and decentralized generation) become more and more widely adopted [3]. Since the industrial and residential sectors are among the largest consumers of electrical energy, decentralized electricity generation has now become a potential solution for satisfying the energy needs locally. In comparison to large-scale wind energy, the cost of deploying a PV system is much higher, and therefore implying that a larger financial subsidy is needed to increase the PV installation capacity by customers [4,5,6]. Microgrids are small size electrical networks built to provide a reliable electric supply and with a better quality for a small number of consumers. They consists of local power stations (micro turbines, fuel cell, small diesel generators, photovoltaic panels, etc), loads, storage batteries and a power management strategy for the supervision and dispatching power flow. They can operate either in gridconnected mode or in isolated mode. T[...]
