The number of power electronics converters connected to electrical networks has been growing exponentially as they are part of all new generation connected to the grid. While the rapid control and fast electronic switching available with this technology offer flexibility in network operation, the dynamic interactions between several of them threaten the operational stability of the transmission grid is a concern. It is required to develop a methodology for identifying the risks associated with the stability and control interaction before a new power electronic device (e.g. Windfarm, interconnector, STATCOM) is introduced to the network The talk will focus on an analytical framework in impedance domain to quantify the interaction between the new plant and the rest of the network for setting additional grid connection study specifications which will include detail technical study to check and mitigate the risks associated with new power electronics interfaced generation. The framework developed is to support MMC technology, control delay, system strength and FRT capability of dynamic voltage support devices and windfarm through technical case study conducted at the research group of Bikash Pal at Imperial College London. Future research challenges and opportunities will be highlighted.

The Production system at Hope provides a means to broadcast worship services to their Church Campuses around the Metro and to several Hope Church Groups around the State of Iowa and Missouri. Also, the services are streamed on the Web. Hope's staff and volunteers strive to have the best quality possible and are looking for ways to improve their skills. This will be a joint meeting with the Central Iowa Section Joint Chapter. Agenda: 5:00 PM – 6:30 PM Tour Bldg: Lutheran Church of Hope, Main Lobby under “New to Hope” sign, 925 Jordan Creek Pkwy, West Des Moines , Iowa, United States, 50266

epop, a goat on the Unix farm (Actually, epop is a programming language & environment.) Jack Pope will provide an overview of some of the clever ways that Forth-like compilers and interpreters are implemented. He will delve into one such implementation called epop.
