With a rapid increase of dispersed generation (DG) like wind power etc. in Japan and around the world, there is a growing need for distributed energy integration (DEI) in the power grid as a reliable and a responsible source. In accomplishing this task, a number of underlying technical challenges need to be addressed successfully. In finding solutions to such technical issues, the role of simulation...
The Danish power system is characterized by a high share of dispersed generation (DG) and wind power plants. Today about 24 % of the electricity consumption is produced by wind turbines and about 19 % by combined heat and power units (CHP). The paper shows, how the Danish transmission system operator (TSO), Energinet.dk, handles the tasks of providing secure system operation today and in future, using...
Dynamic demand-side management of domestic electricity loads is of increasing interest in the context of the growth of renewable energy in general and the expansion of distributed generation and micro-generation in particular. This paper explores its potential with emphasis on the UK. The different services that dynamic or near real-time load adjustment can provide are reviewed and its system value...
A partnership program developed between Maryland Energy Administration and Frostburg State University is described. The main purpose of this partnership is to promote residential electric generation using solar and wind power in Western Maryland. Activities include construction of a grid-tied hybrid demonstration system, development of a knowledge base to assist the local community to develop their...
This paper presents the progress in distributed generation in Korea. The government policy has emphasized mainly on three different renewable energy sources, namely, hydrogen and fuel cell, photovoltaic, and wind power. Concerning renewable energy, the government plans to replace 5% of the primary energy source by the year 2011. The road map for the three major renewable energy sources is presented.
In recent years, distributed generation, as clean natural energy generation and cogeneration system of high thermal efficiency, has increased due to the problems of global warming and exhaustion of fossil fuels. Many of the distributed generations are set up in the vicinity of the customer, and there is the advantage that this decreases transmission losses. However, output of natural energy power...
