Recent advances in enabling technologies such as power electronics, electric hybrid systems, energy storage systems, energy management systems, variable frequency drives, and DC bus duct systems have allowed electrical system designers an opportunity to develop new electrical system designs with distributed DC systems that can be optimized in terms of fuel efficiency, reduced emissions, enhanced system...
This paper describes a load management system for tactical microgrids that improves load balancing across three phases and provides load shedding capability. A single hardware design comprised of solid state relays enables switching of loads to specific phases during operation or, alternatively, shedding the loads to reduce demand. Load shedding can help alleviate overloading of generators and load...
In this paper, we propose a parametric quadratic programming method for the day-ahead scheduling of power generation and battery charge cycles, where the prediction uncertainty of power consumption, photovoltaic power generation, and their half-hourly change is modeled as a parameter vector lying in interval boxes. The parametric quadratic programming is formulated as the problem of finding the interval...
Hybrid between PV and Generator with battery is one common technology that has been used in the world due to meet the system with the presence of renewable energy. These systems are typically used in isolated area or areas away from the grid. In this paper the hybrid PV-Generator with battery power plant will be designed for Aha Village in Morotai Island which is one island in Indonesia that located...
This study focuses on one of the main concepts regarding strategies to be adopted to reach the European policy targets, regarding Green House Gas emissions (GHG). The subsidization of renewable energy sources showed its limits, due to the fact that such power plants can create several problems to the power grids they are connected to, and for this reason the implementation of new or more advanced...
This paper proposes the Self-learning Cuckoo search algorithm to solve Multi-Area Economic Dispatch problems. The main objective of multi-area economic dispatch is to minimize the total fuel cost while satisfying balanced-power constraint in each area and limitations of generators and transmission lines. In addition, the proposed method is an improvement of the Cuckoo search algorithm with a new strategy...
A market-based control approach is presented for the control of power flow within an electric ship. The proposed control method consists of an artificial market in which various actors (a consumer and firms) behave according to microeconomic principles. Each piece of equipment within the engineering plant will behave as a firm, attempting to maximize its profit. The commanding officer will behave...
This paper presents two fuel optimization approaches for independent power producer (IPP) power plants consisting of multiple diesel driven generator sets (DGs). The optimization approaches utilize assumed information about the fuel consumption characteristics of each DG in an effort to demonstrate the potential benefits of acquiring such information. Reasonable variations in fuel consumption characteristics...
Monitoring of diesel generators is an important part of the management program of electricity utilities as well as telecommunication companies' in-order to have their cellular towers and base transmitter stations up all the time. A reliable remote monitoring method over the on-site method is always desirable so that managing of time and resources can take place as efficiently as possible. This paper...
One of the most critical situations in the operation of medium and low speed synchronous generators appears when they are subjected to torque imbalances. This could be the case of internal combustion engines driven generators. In these engines, torque has a periodic oscillation due to variations in the combustion process and pressure development between cylinders. Consequently, a fuel excess or a...
This paper elucidatesa new improved optimization algorithm for economic Load dispatch (ELD) problem using self-adaptive real coded genetic algorithm. The ELD dilemma is formulated as a single-objective on-linear constrained optimization problem gratifying both equality and inequality constraints. The regeneration of population practice is integrated to the conventional real coded genetic algorithm...
Current auxiliary power unit (APU) system in aircraft is heavy, noisy and inefficient, so a new form of power source to replace the engine mounted generator technologies is in demand. As a green power source, fuel cell is discussed in this paper to study the feasibility of the system as an APU. This paper investigates different fuel cell applications, and qualitative analysis shows that proton exchange...
The Cretan power system is the largest autonomous power system in Greece, and it consumes around 5% of the total Greek electricity demand. It contains a large number of conventional power stations that are combined with significant installed capacity of wind farms and photovoltaics. This paper is evaluating the effect of a large wind-hydro hybrid power station installation in this system. The analysis...
The aim of this article is that of proposing a novel approach for the control of an electric gas-generating unit for large power generation. The main objective of the control of a gas generating unit is that of controlling power production, in order to meet the requirements of grid operator, and keep the temperature of the exhaust gasses at the turbine outlet at a constant value in order to allow...
A literature review on applications of biologically inspired algorithms such as Differential evolution (DE), Invasive weed optimization (IWO), Cuckoo search algorithm (CSA), Firefly algorithm (FA) and Krill herd algorithm (KHA) has been presented. Economic dispatch (ED) is one of the key optimization problems in operation of power system. Aim of the ED problem is optimal allocation of power demand...
The Indonesian government (GoI) applies the cost recovery concept in the upstream sector of the oil and gas resources. It postulates the expenses spent by the contractor during exploration and exploitation activities will be settled through production sharing scheme. The cost includes the compensation for the production equipment and utilities, not to mention the power generator. When the oil-and-gas...
Increasingly stringent regulations on emission control and energy efficiency operations drives the maritime industry towards hybrid solutions incorporating energy storage and other alternative energy sources into marine power systems. In particular, commercial all-electric hybrid vessels with dynamic operations such as harbor tugs often face significant challenges in power management control to maximize...
Transport sector could play a relevant role in future energy decarbonisation pathways contributing to energy consumption and pollutant emissions reduction. Planning in the transport sector requires that policy makers be supported with scientifically sound tools, which are able to take into account the peculiar aspects of transport system analyses, especially at urban scale. One of these peculiarities...
This paper proposes the co-location of gas reciprocating generator sets with High Power Charging (HPC) stations for Battery Electric Vehicles (BEVs), to offer a low carbon source of heat and power which could help to meet national government transportation and heating strategies while minimizing the impact that HPC systems will have on the power network.

Nowadays, mini-grids can provide reliable and cheap electricity also to far communities of developing countries. Diesel generators can ensure backup power, in addition to renewable sources and energy storage devices. However, poor infrastructures, severe weather conditions and a difficult procurement chain can strongly influence the fuel delivery, thus reducing the continuity of supply. The present...
