Power generation growth based on natural gas fired power plants (NGFPPs) has lead to increasing interactions between electric power and natural gas industries. More companies are progressively and simultaneously participating as big players in both markets. However, each company has traditionally been settled in one side, holding a particular competitive advantage: electric power generation companies...
Agriculture is energy-intense, but also has a huge potential for generating energy directly at the point of use from renewables, e.g. biomass, photovoltaics and wind. In this paper, we investigate two models of collective arrangements among farmers in the federal state of Styria, Austria. These arrangements have the purpose to facilitate adoption of photovoltaics on farms. We contrast the two models...
Market development of electric vehicles in the coming years is a highly relevant issue for many stakeholders, e.g. automobile- and energy-industry, investors as well as policy makers and the public. The market forecasts, however, differ strongly and underlying assumptions are often hard to find. Furthermore, for stakeholders from such diverse fields it can be difficult to convey their own assumptions...
Because of global warming and shortage of fossil fuels, much attention has been paid to plug-in electric vehicles (PEVs) worldwide in recent years. With possibly millions of PEVs on road in the future, it is essential for power network operators, especially distribution network operators, to implement coordinated PEV charging. In this paper, an optimal charging method is proposed for PEVs to maximize...
Incentive regulation is moving towards new schemes where standard efficiency mechanisms are combined with output-based incentives (related to quality of supply, sustainability and innovation). Assessing performance of regulated utilities requires models capable to account for these different regulatory objectives. Benchmarking analysis has been in use for a long time; however, whether these models...
World Bank-financed photovoltaic (PV) electrification projects principally aim to improved electricity access for populations in remote areas that are unlikely to be reached by grid extension within a reasonable time frame. The business models adopted for commercial PV dissemination are classified as a dealer model and a fee-for-service model. Drawing on experiences in implementing these projects,...
Market power analysis is one of the major issues facing regulators of wholesale electricity markets. The exercise of market power both distorts wholesale price signals and reduces the efficiency of the operation of and investment in the wholesale electricity market. This paper deals with a systematic way for quantifying and visualising market power. The paper first proposes three indicators termed...
In the market, the future competitive forces of power companies depend on their abilities of managing and using the risk. The electricity market of our country has formed new operation mode that the power grid is divided into three levels which are the national network, regional network and provincial network. Provincial power company will face the risk of higher electricity purchased costs and insufficient...
This paper deals with the modeling of electric markets whenever certain imperfections pollute the supplied electrical energy. These imperfections are described in terms of a lack in power quality, and must be quantitatively introduced in the model as an additional economic factor which influences the consumption of electrical energy and its market price. Therefore, the main intent of this paper is...
It is commonly believed that telework is good for the environment because it saves energy through reduced commuting. Millions are teleworking worldwide. Some peer-reviewed publications in the last decade have shown that the principles of life-cycle assessment (LCA) have to be applied to telework (just like to other products and services) in order to arrive at a comprehensive assessment of all the...
This work deals with strategies optimization for suppliers in the electricity market characterized by the presence of a large supplier competing against small suppliers acting as a fringe. Power bidding is a game process with incomplete information for costs are unknown to competitors. Based on the hypothesis that the supplier's bidding strategy is a function of cost, the market clearing price is...
The development environment in our nation has been changed for generation companies in the electricity market. So that, the old management style of the power equipment maintenance can not adapt to the new environment. In this paper, In allusion to the conflict between domestic power generation equipment for the maintenance of system reliability and economic interests, the long-time maintenance scheduling...
Under the electricity market, there are some new changes for provincial grid companies to purchase power. Besides most fixed contract of purchasing power, some free purchase room is existed in certain condition. At first overall thinking of purchase optimization in provincial grid corporation is discussed in this paper. Then a system of discriminated process is puts forward, which helps to establish...
Smart Grid is the research focus of today's power industry. Demand Response (DR), as one of the primary components of the Smart Grid, has got much attention from the utilities and the consumers. In the electricity market with opening demand side, on the basis of optimal spot pricing with Primal - dual interior point algorithm, the distribution pricing model considering Demand Response was formed,...
With the development of electricity market fair competition becomes the most important and basic principle. Although the transmission losses account for a very small part in the full cost of the electric transactions, how to allocate the transmission losses has great effects on the special trade and the network customers. The paper proposes the analytic expression of power components distributing...
This paper addresses the generation expansion-planning problem describing a model that generation companies and regulators can use to get insight to this problem and to more completely study and characterize different investment decisions. The simulation model considers a number of possible generation technologies and aims at characterizing the corresponding investment plans from an economic point...
Electric power generation market has game characteristics such as players with incomplete information and bounded rationality. To meet such requirements, evolutionary game theory is applied. Based on the differences among units status of generation companies, modeling and simulation are carried out for the biding strategy of each generating unit by random pairing with another member of game population...
This paper presents and motivates the development of a techno-economic education package, consisting of two simulation games, to simulate both the trading and the generation of electricity in a liberalized market. Six attributes (storytelling; players as problem solvers and explorers; feedback; challenges that fit the student characteristics; competition; appropriate graphics and sounds) are relevant...
Due to geographical position and location, the Croatian power system has an opportunity for cross-border electricity trading. Cross-border transaction causes additional power flows in the internal Croatian transmission network that can lead to congestion. Congestion occurs when a transmission line between two locations is loaded close to its limit. In order to investigate influence of cross-border...
As independent economic entity, each power generation company in China participates in current electric power market competition by price bidding. Multi-population replicator dynamics of evolutionary game theory is applied to model and simulate power generation companiespsila discriminatory and bounded rationality bidding strategies according to different generating set status in a power market. The...
