Today, electrical innovation is the most needed both for own use and for industry. Therefore, researchers create various innovations to improve efficiency. There are so many innovations being developed that the efficiency of the power plant can be improved. One such innovation is the use of turning gear operations in generation to rejuvenate generator turbines and improve efficiency. The purpose of...
This work explores the use of thermo-acoustic system as alternative technology for electricity generation. This technology is proposed as a potential replacement for low-cost electrical power generation because of its simplicity and lack of moving parts. Thermo-acoustic generators providing clean electrical energy to power small appliances. The energy conversion from heat into sound wave is done within...
For more than 30 years, Lebanon has suffered from insufficient electric production. While the world is shifting towards total dependency on renewable energy, Lebanon is still facing the disastrous situation in its electricity sector. This paper suggests a plan of building diesel power plants and engaging them to the public grid. To achieve this, a supervisory control method (SCM) including a frequency...
Lumen is an exciting way of explaining and demystifying energy and electricity. By modifying the popular computer game Minecraft, electric blocks can be used to create physically representative constructions. Minecraft is essentially turned into a real-time interactive grid simulator. Sources such as solar panels and combustion engines can be connected with cables to loads such as multicolored LEDs...
The increase in renewable energy generators introduced into the electricity grid is putting pressure on its stability and management as predictions of renewable energy sources cannot be accurate or fully controlled. This, with the additional pressure of fluctuations in demand, presents a problem more complex than the current methods of controlling electricity distribution were designed for. A global...
Bangladesh, being a typical developing country, has undergone the energy crisis situation for a very long period of time. The energy system of the country has gradually being improving with the electricity accessibility ratio increasing year by year. The study has been based on different analytical information and data analysis regarding the Energy Market of Bangladesh. The study investigates on the...
The paper presents the possibility of using geothermal energy for electricity production at average temperatures. The authors considered two options for their study, namely binary cycles (organic Rankine and Kalina) and the thermoelectric generators. After a comparative study for the proposed solution, was chosen Kalina cycle and was proposed a solution for a geothermal power plant. The advantages...
Off grid hybrid renewable energy based power systems for rural electrification has become an attractive solution for areas where grid electricity is not feasible. Hybrid systems use several generation technologies, therefore the selection of proper technologies and optimum sizing of the components has become of great importance in reducing the overall cost and increasing the reliability of the service...
Adequate generation reserves are needed to avoid failures in case electricity demand exceeds available online generation capacity. Properly determining generation reserves promotes efficient resource allocation. This paper establishes a model to purchase optimal quantities of firm energy and of various reserve capacities for a dispatch period to cover randomness in demand considering transmission...
Renewable energy developments have significantly influenced to the power system planning. In particular, in the last decade, renewable energy sources are considerably increased due to the supportive renewable energy policy worldwide. In this paper, an economic model is proposed to analyze the electricity market equilibrium under the impacts of renewable energy policy. In addition, the model reveals...
Economic Dispatch is an important optimization problem in power system planning. This article presents an overview of the economic dispatch problem, its formulation, and a comparison of addressing the problem between the vertically integrated market and the liberalized market environments.
With the shale gas revolution, coal retirements, environmental regulations, and increasing renewable energy resources, the interdependency of natural gas and electricity has grown significantly. Interdependency challenges, such as mismatched market schedules and disparate market operations, require quantitative modeling in order to garner insights into the effectiveness of various solutions. In this...
In this paper, a much more detailed representation of the nation's electricity system than has been traditionally used in policy models is employed. This detailed representation greatly increases the computational difficulty of obtaining optimal solutions, but is necessary to accurately model the location of new investment in generation. Given the proposed regulation of CO2 emissions from US power...
This paper proposes hydropower potential sites for a resort island located in the South China Sea. Furthermore, the effects of seasonal climate to hydropower generation are also discussed. The resort island selected is Tioman, as it represents the typical energy requirements of many resort islands in the South China Sea. The island relies mainly on diesel-fuel for electricity generation. However,...
A hybrid system utilizes several energy sources to generate electricity. This paper proposes combination of two renewable energies i.e. micro-hydro and photovoltaic for energy independent village application in Dusun Mergosari, Pesawaran Indah Village, Pesawaran Regency, Lampung Province. Previously, the village was only supplied by one micro-hydro generator through a long feeder line with high voltage...
Hybrid renewable energy systems (HRES) have become more and more popular, especially for isolated regions. Various renewable energy resources are utilised to produce energy for different usage. This paper discusses the design of HRES for the Ha'apai island group. Possible renewable resources for electricity generation are investigated and the optimum system configuration at the lowest capital expenditure...
The bid-based dynamic economic load dispatch problem (BBDELD) is an optimization problem that arises in the modern context of a de-regulated national energy market, and involves matching bids from competing generating companies to the demands of consumers (regions) so as to maximize a measure of ‘social profit’. We present a novel approach to solving the BBDELD, and introduce a large-scale test-case...
The availability based tariff (ABT) structure introduced by Government of India established inter region grid discipline through Central Electricity Regulatory Commission Regulation 2009. Using this regulation the over /under injection by the generators during off-peak/peak hours are discouraged and the frequency is maintained within a range amongst five regional grids of India. This work follows...
The supply of electricity to the rural villages in the south of Algeria where the dispersion of population is very important and the increase in the rate of consumption of electrical energy constitute two major problems encountered by the company of electricity in Algeria. Electricity generation in large southern Algeria is based primarily on diesel power production with enormous technical, economic...
Optimal allocation of DGs is currently one of the major challenges for power system engineers. Determination of the proper location of DG units is imperative to maximize their benefits. This research investigates optimal placement of multiple DG units to obtain the most stable system. The proposed method is based on an advanced voltage stability analysis method: the new modified Voltage-Active Power...
