Abstract

The development of Microgrid states the problem of choosing the optimal technologies for its composition. This paper is to present cost based demand-side management methods for the Microgrids with Distributed Generation sources to optimize their operation. While implementing variable pricing models the aggregator should take into account characteristics of different Distributed Energy Resources (DER) (diesel engines, gas turbines, fuel cells, solar panels, small hydropower plants and wind turbines) and LCOE for each type of DER to stimulate each local electricity market participant separately. The system Microgrid using three diesel generators and the option of replacing one generator with a solar electric and wind generator installation was considered. Розвиткок Microgrid систем викликав появу проблем пов'язаних з вибором складових для забезпечення оптимальної структури означених систем. У даній статті представлено цінові методи керування попитом для Microgrid систем з джерелами розосередженої генерації для оптимізації їх роботи. Обґрунтовано, що під час впровадження різноманітних цінових/ тарифних моделей агрегатор повинен враховувати характеристики різних розосереджених джерел енергії (РДЕ) (дизельні генератори, газові турбіни, паливні елементи, сонячні батареї, малі гідроелектростанції та вітрові турбіни) і LCOE для кожного типу РДЕ, щоб стимулювати до участі у програмах керування попитом кожного учасника локального ринку електричної енергії окремо. Розглянуто Microgrid систему з використанням трьох дизель-генераторів і варіантами заміни одного генератора на фотоелектричну або вітрогенераторну установку.

Abstract

The paper presents a new approach to energy indicator determination, such as specific fuel consumption and energy efficiency of the power plant. The essence of the new method is to determine the instantaneous power of the installation with subsequent data processing. The use of this method allows establishing the dependence of specific energy indicators on the generating unit load levels. The established distribution allows defining optimum parameters of experimental setup and consumption at various loading levels. The highest specific energy consumption of fuel is observed (1189–1297 g /(kW·h) and 962–1147 g / / kW·h)) at the lowest and the highest load for different fuels. Experimental data show that fuel without ethanol impurities can generate more electricity, which should be used at higher demand. [ABSTRACT FROM AUTHOR]

N-(Carbamoyl)-1-aryl-2,3,4,5,6,7-hexahydro-3-hydroxy-6,6-dimethyl-2,4-dioxo-1 H-indole-3-carboxamides upon dissolution in DMSO or DMF undergo a reversible isomerization to 5-(2-arylamino-4,4-dimethyl-6-oxocyclohex-1-en-1-yl)-5-hydroxypyrimidine-2,4,6(1 H,3 H,5 H)-triones. [ABSTRACT FROM AUTHOR]

28. Oscillation efficiency and frequency properties of intervalley-electron transfer GaN diodes.

Author

Botsula, O. V., Prokhorov, E. D., Zaichenko, S. V., Pavlenko, L. I., and Motorniuk, S. A.

Abstract

The results obtained from simulating GaN-based intervalley-electron transfer diodes having different types of cathode contacts (ohmic, metallic, with a lower-concentration region). The main-particle Monte Carlo method was used to analyze electron processes occurring in a diode. The diode parameters and an operating frequency were selected from the condition for obtaining a maximum oscillation frequency. The maximum oscillation frequency for all type of considered diodes is shown to be as high as 600 GHz. [ABSTRACT FROM PUBLISHER]
