Вторая часть статьи посвящена решению задачи подавления влияния внешних возмущений в энергетической системе на ее выход. Эта задача решается на основе метода...

With the increased use of wind energy for the power generation several TSO have increasing difficulties for congestion forecasting due to the unpredictable nature of the energy source. An actual method used to deal with days-ahead congestion planning is based on an order of disconnection of the...

На основе метода размещения полюсов замкнутой системы в заданной области на комплексной плоскости и H∞-метода формирования контура с помощью аппарата линейных...

In this article, an improved integrated battery energy storage system (BESS) controller for distributed energy system is presented. The BESS is integrated in parallel with the full wave bridge converter into the distributed energy system network. In a normal operating mode, the BESS serves as a...

This paper will describe the possibilities of coordinated control and management for different wind farm concepts to guarantee that operational set points of active and reactive power, specified by the Spanish transmission system operator (TSO), are reached. This coordinated control has been...

This article describes a direct current (DC) isolated network that is infed with distributed generation from renewable sources and cogeneration units. The sources are connected to the network via DC/DC converters to keep the voltage within a defined range and to ensure the required power flow....

Wind energy is a prominent area of application of variable speed generators operating on the constant grid frequency. A modern wind energy system of this type consists of a surface mounted permanent-magnet generator with a frequency converter, which allows variable speed operation. The maximum...

At the moment, the control ability of wind farms is a prime research concern for the grid integration of large wind farms, due to their required active role in the power system. This paper describes the on-going work of a research project, whose overall objective is to analyse and assess the...

This paper presents a methodology for effective control of fuel cell devices connected to an electric utility distribution network. A controller is developed for a fuel cell power plant to assist the conventional generators to damp out oscillations, which is possible by utilizing the fast...

A multi-machine multi-converter system formalism has been proposed to describe systems composed of several electrical machines and converters. This description points out coupling elements, which have to distribute energy. Control structures have already been proposed for systems with downstream...
