The article is devoted to the long-term improvement of the Russian gas industry development model for the period of up to 2035. New approaches to forecasting gas production at major fields, transportation of pipeline gas and spot market gas purchases are being updated.
This paper presents an application of Genetic Algorithm (GA) to solve Economic Load Dispatch problem which aims to determine minimum fuel cost and Environmental Load Dispatch problem which aims to determine minimum gas emission for required energy production of the chosen power system. Test system is chosen as IEEE-30 bus system which includes 6 generators with necessary values given for ease of simulation...
The Power-to-Liquid (PtL) concept offers the potential to interlink the power and fuel market by producing high quality fuels from electricity and CO2. In addition, gaseous by-products from fuel synthesis can be used to generate electricity in peak load hours. In this work, a PtL concept comprising of a reversible solid oxide cell (SOC) is presented and evaluated in terms of 2014 fuel net production...
Biorefineries convert biomass from a wide variety of easily available feedstock to a potentially wide range of products (including biofuels) in a sustainable and environmentally friendly way. In this work, we consider the integration of a biorefinery to consume the biomass produced from a kraft pulp and paper plant and maximize its economic performance while minimizing the environmental impact. These...
Driven by the need for actions to successfully fight and prevent the consequences of climate change, the concept of integrated energy (or multi-energy) systems is receiving increasing interest across the world. This concept includes optimal integration of multiple energy infrastructures such as for electricity heat, gas, and so on, partial electrification of heat and transport, and a shift of energy...
Increasing shares of renewable energy sources in the German electricity market increase the need for flexibility in order to reduce curtailment of low variable cost RES generation. Power-to-Heat (PtH) is an option to provide additional flexibility. This paper evaluates the flexibility gain a PtH installation provides using the example of adding it to a district heating facility. Therefore we compare...
This paper outlines the economical issues related to the transition of the energy generation for a real MV/LV distribution system from a ‘fuel based’ one to a distributed and smart ‘renewables based’ one. It is the prosecution of a companion paper, which addressed the technical issues connected to such transition. The study has been carried out by University of Palermo and ENEA (Italy), on a portion...
The Lebanese Electric Power System (LEPS) suffers from technical and financial deficiencies that required the development of a policy paper to rescue it from its drastic situation to a new sustainable, reliable, and efficient delivery of electricity. An energy policy that includes ten strategic initiatives and 42 action steps that are integrated and correlated to cover the sector's infrastructure,...
It is opinion that climate change on the planet is largely dependent on the increase of greenhouse gases in the atmosphere and that this effect is related largely to human activities that make CO2. Reducing the discharge of CO2 has therefore become a common objective of the international community, including China. There are various actions that are proposed for the reduction of the gas: increased...
Sustainable energy development evaluation can help the government ascertain the top-priority problem in the process of sustainable energy development and meanwhile, it offers effective information to the decision makers and public. The screening of sustainable energy development evaluation indicators and the construction of indicator system are the important precondition for sustainable energy development...
The processes and routes of syngas production from biomass gasification were first outlined, and the key processes of this technology were highlighted in the paper. Simultaneously, the cost of syngas production from biomass gasification was evaluated to be RMB 1.05/Nm3 when the handling capacity of gasifier, material cost and system operating rate is separately fixed to be lton/h, RMB 250/ton and...
Forest biomass energy resources, as alternatives to fossil energy, are green renewable energy in the future. State-owned forest areas of Heilongjiang, as China's key state-owned forest areas have great development potential of forest biomass resources. This paper takes Longjiang Group as the research object, using data envelopment analysis (DEA) to test the development efficiency of forest biomass...
The New England power system is highly dependent on natural gas-fired generating units. As a result, the price of natural gas drives the price of electrical energy and the amount of environmental emissions. The system benefits when the price of natural gas is low. However, there is a need to mitigate the risks of high prices of natural gas through the diversification of fuel supply, especially as...
In the modern competitive electricity supply industry, there is a renewed interest in algorithms that can provide fast and optimal solutions for savings in operation costs. A novel methodological strategy incorporating the priority list is proposed to provide efficient solutions. Thus, we call the proposed method as methodological priority list (MPL) method. The MPL is simpler and more efficient than...
The depletion of gas with its use is a great concern of Bangladesh. Electricity sector consumes 47% of total annual use of gas. Because of the peculiar input energy requirement characteristic of thermal units with their output the generating units are operated such that the total input energy requirement is minimum in a power system. As load management through load shedding, is a common phenomenon...
The depletion of energy resources, the quest for security-of-supply and the need to mitigate climate change may require or invoke for a transition of energy infrastructures. We conjecture that the phenomenon of transitions is not sufficiently understood to merit high expectations from transition management since energy infrastructures are complex, large scale socio-technical systems. Transitions are...
Energy shortage, soaring oil prices, and climate change stimulate the research and development of alternative energy resources to sustain economic growth. Biofuels, such as biodiesel and biomass-based alcohol fuels, are examples of such alternatives. However, whether these energy alternatives can achieve commercial success highly depends on how sustainable they are. This paper reports an on-going...
The electricity generation in Pakistan is predominantly based on oil and gas. Three major hydroelectric power stations cater for the base load. Sky rocketing oil prices warrant the adoption of a balanced fuel mix for power generation based on indigenously available and exploitable fuel sources. The framework for the development of most economic, least cost fuel mix for power generation in Pakistan...
The purpose of this paper is to analyze in time the dimensioning of the electric supply, in relation to a growth of the energy demand supported by a regional economic growth. In France, Corsicapsilas island constitutes a specific case of study, from its statute of area not inter-connected with the electrical network of the metropolis. First of all, we will distinguish the principal technological innovations...
Oil spills in the ocean are one of major environmental concerns, especially in the costal waters. Many satellite sensors, including optical sensors and microwave sensors, have been used to detect oil spills which often exhibit different feature in the satellite images compared with the surrounding waters. In this study, we used texture feature analysis to detect oil spill using MODIS and SAR images...
