Inspired by potential application in power systems and a fully distributed primal-dual method, we investigate how a novel distributed optimization algorithm can be used to solve the dispath response problem in power systems with a distributed manner, whose main target is to minimize the generation cost of the whole network. The problem we study here can be formulated as a kind of optimization problem,...
A home solar power system for micro electric vehicles (EVs) is one of the important technologies to realize a sustainable energy society. The aim of this paper is a demonstration of a high performance digital control phase-shifted full-bridge converter connected between solar panels and the dc-bus line. Since the voltage in a home storage battery and EV battery is around 72V in some products, the...

Undeniably, the focus of several works revolved around finding a process of unification to follow along the modeling of mechatronic systems. This paper is a part of a general research designed to apply topology for the modeling of complex mechatronic systems. Notably, a topological approach to model a Wind Turbine is adopted in this study. The Wind Turbine model under study is modeled using a topological...
This paper presents comparative evaluation and explores the different technologies suitable for the implementation of the Medium Voltage Direct Current (MVDC) electrical supplies for the marine on-board electrical distribution network. To realize the MVDC supply in the range from 5 kV to 25 kV, various technological choices are available during the design process and have a direct influence on the...
Economic load dispatch (ELD) is one of the main tools for optimal operation and planning of modern power systems. To solve effectively the ELD problem, most of the conventional calculus methods rely on the assumption that the fuel cost characteristic of a generating unit is a smooth and convex function, resulting in inaccurate dispatch. This paper presents the design and application of a new efficient...
Micro-grids are bits of a power circulation organize that supply various loads, and incorporate distributed generation (DG) like: wind and solar generators. Optimal power flow (OPF) is considered with the goal of limiting either the power circulation misfortunes, or, the cost of influence drawn from the substation and provided by (DG) units. This paper analyzes two systems: a system with no transmission...
The paper has as first objective the overview of the active distribution networks for the future, their viability with existing equipment and components. The presented applications are intended for industrial-type networks with local power generation in view of their efficient integration into an intelligent distribution network. The main scientific goal of the paper is to test the stability issues...
One of the main issues that still emerging as the most complex fundamental problems in power system operation is Economic dispatch (ED). This paper presents the application of Fruit Fly Optimization (FFO) algorithm technique for solving ED problem. The FFO algorithm is applied to minimize the cost of generating units by allocating the most optimum value of real power for a specific generating unit...
Economic dispatch is considered as one of the critical advancement errand and operational choice which gives a financial condition to control framework. The principle emphasis of economic dispatch is the means by which a power system network can be arranged with the goal that we have minimum cost of electric generation to take care of the load demand, while meeting all the balance and imbalance constraints...
This paper presents aspects of the technical evolution in micro-networks efficiency with respect to the power quality and system availability. Different potential approaches for market using are shown. The environmental and economic effects of the micro-networks depends of their implementing phases, like design, commissioning and testing. It can be a lot different than the normal main grid, depending...
The study of the carbon obligation allocation among different members in the power system holds significant theoretical and practical value. Existing methods for carbon emission estimation usually attribute the emission responsibility to single side (either generation side or demand side). However, both the generation side and the demand side should take the responsibility of carbon reduction and...
This article proposes an analysis of the technical and economic feasibility of a Clean Development Mechanism (CDM) project for the generation of electricity through the use of biogas from landfill through the use of microturbine technology. In order to obtain the baseline and project scenarios, the methodology ACM-0001 was used, which is specific for the use of landfill biogas. For the economic viability...
The transition from the traditional power grid to the smart grid improves reliability, performance, and management, while simultaneously increasing its susceptibility to cyberattacks. One of the biggest weaknesses in grid security is the human agent responsible for its maintenance and operations. As such, it is crucial to embed hands-on understanding of grid operations and security, especially for...
A city's critical infrastructure such as gas, water, and power systems, are largely interdependent since they share energy, computing, and communication resources. This, in turn, makes it challenging to endow them with fool-proof security solutions. In this paper, a unified model for interdependent gas- power-water infrastructure is presented and the security of this model is studied using a novel...
This paper proposes a method to modulate the power output of converter interfaced generators (CIGs) according to frequency variations. With the proposed approach, CIGs can successfully engage in the primary frequency regulation of a power system. The approach is a variation on the traditional droop-like proportional controller where the feedback signal is a global frequency measurement instead of...

We present and analyze distributed control schemes for frequency regulation in a smart grid. We use energy storage, conventional generators, wind generators and demand response to provide frequency support while having no communication or data sharing between them. All participants observe the system frequency and act independently in a decentralized manner to provide frequency regulation. We also...
