   Decentralised Energy Distribution

Abstract: The implementation of more and more distributed power sources into the electric power grid (Wind, Solar Power, CHP etc.) may has the impact of an "inverse" electric power flow compared to the origin design of the grid. This and the increasing share of distributed power sources concerning the total installed electric power generation lead to changes in requirements to the power conversion units. In the past, at a low share, these units had been simply switched off, when grid failures occured. This situation has been completely changed. Grid connected distributed power sources have to be capable for grid control, fault ride through and ancillary services as other power sources in the upper power range do. The presentation gives an overview of the basics, grid code requirements and structural solutions for the power conditioning units of solar and wind power converter installations. The problems of lower power units to fulfill some of the requirements are covered.

   Energy Storage facilitating the integration of decentralized electricity grids â€“ Functional Requirements and Solutions of selected examples

Abstract: Power generation and distribution are expected to become increasingly decentralized and include a significant portion of renewables, at least on parts of the grid. Energy storage by means of electrochemical accumulators can fulfill a variety of functions and contribute to the successful and growing integration of renewables into our electricity landscape. The presentation will browse the spectrum of energy storage applications in decentralized networks from energy dispatching to grid stabilization, including: oGrid connected photovoltaic systems oWind-diesel hybrid systems oStabilization of medium voltage grids On one end of the spectrum, typically in PV applications, dispatching energy consists of storing energy at its time of production, and to release it at a time of use. On the other end, energy storage can stabilize a grid (voltage, frequency) by simply smoothing very short term variations between generation and use of energy and power (typically milliseconds to a few minutes). In reality, there is a continuum of variations between the two ends of this spectrum, depending on the characteristics of the generating source(s), the load(s), and the grid or micro-grid. We will analyze the functional requirements (operating pattern, typical voltages, power, etc.) of different real applications and explain how to select and size an adequate battery solutions, providing details on battery technology, operational performance, life time, economical analysis and perspectives. We will refer only to existing cases and report about operational experience and lessons learnt.
