A mathematical model has been developed to describe an autonomous energy system including energy plants (technologies) of two types: energy conversion (transport) and energy (energy carriers) storage. At the conversion plants, primary and secondary energy is converted into final energy and secondary energy of another type; in energy storages, secondary energy is accumulated for its further utilization. The mathematical programming problem is formulated; the objective function is the total discounted costs of the system creation and operation. The variants of the optimal structure of an energy system, including a diesel power plant, a biomass-fueled power plant and wind turbines, were found, depending on the price of diesel fuel and wind speed. © The Author 2010.

The paper considers mechanisms for organizing free trade in the electricity market, which are based on submitting bids of energy consumers and producers to the market operator. The research focuses on the models of market operation as a double sided auction where participants have different rights (price takers and active competitors). The authors discuss and compare possible strategies of generator behavior that lead to different equilibrium situations and correspond to Cournot model and the models of supply function equilibrium, and a perfectly competitive equilibrium. The mechanisms are tested on the basis of the Siberian electric power system, Russia. © 2014 Published by Elsevier B.V. Source

A theoretical study of the equilibrium velocity of sound in the liquid-vapor mixture containing the close-packed layer of spherical particles has been carried out. Thermodynamic relations include a description of a non-stationary heat transfer between the mixture and particles in compression half-wave. The theoretical model allows explaining the experimentally observed significant reduction in the equilibrium velocity from its adiabatic value at the increase in vapor content of the mixture. The calculated results agree with experimental data obtained in the vertical channel at filtering the liquid-vapor mixture in a close-packed layer of spherical particles of borosilicate glass and steel. © 2013 Pleiades Publishing, Ltd.

Russia's national interests require strengthening its energy cooperation with China, Japan, Korea, and other countries in Northeast Asia. Russia needs a balanced well thought out and scientifically based strat- egy for economic and energy cooperation with these countries. The eastern regions of the country, such as East Siberia and the Far East, with their powerful economic and energy potential, are the outposts in the implementation of Russia's national interests in this strategically important region of the world. The article shows the features of the development of Russia's economy in the new economic conditions, which have caused a revision of priorities in energy policy. The initial conditions, targets, and strategic directions of the energy sector are oriented to the East of the country. There are specific proposals on the necessary conditions and incentives for successful implementation of Russia's Eastern vec- tor energy strategy and priorities of its international cooperation. © Pleiades Publishing, Ltd., 2014. © B.G.

Bilateral forward contracts are generally used in electricity markets to stabilise prices and hedge electricity shortage risks. A contract party is able to draw electricity from the contract and resell it to the day-ahead wholesale and retail markets. Contract parties schedule electricity deliveries over contract period to obtain the highest profit and estimate the acceptable contract price. Two types of contracts are introduced as a way to coordinate interests of the contract parties. The study formulates optimisation problems for contract scheduling. The stochastic dynamic programming technique is proposed as a numerical method for the problem solving. An algorithm based on preliminary construction of revenue functions is developed. A numerical example demonstrates the efficiency of the algorithm. © 2010 © The Institution of Engineering and Technology. Source
