“…All demonstrated concepts imply major changes for network and generation unit operators based on present network operation strategies and requirements. The control concepts were developed on the basis of real network data in a network simulation environment, to allow a better use of network reserves [6], [21], [22].…”

This paper describes the process of developing and validating controller concepts using real-time simulation capabilities. The process from the proof-of-concept to the prototype and finally to the realization and the advantage of testing in a realtime simulation environment is demonstrated in a test case. The test case is based on an example in the safety critical domain of electric power systems -the coordinated voltage controller of the DG-DemoNet project. The possibilities and advantages of controller-hardware-in-the-loop (C-HIL) concepts compared to offline simulation are discussed.

Optimizing the energy system is vital for supply safety and efficient operation. One part of such optimization efforts are demand side measures. This article discusses a simulation platform for automated demand side management, i.e. automated load management. Up to now, the strategies and algorithms that decided where and when to take influence on the loads were very primitive. The complexity of the system did not allow for intuitively designing smarter algorithms. As the energy system is a wide area distributed system, questions about system stability, SCADA (supervisory control and data acquisition), reaction times or the relation to the wider environment (customer processes, energy market, etc.) are very difficult to research. The presented prototype is intended to offer a research platform for evaluating potential algorithms for their real-world usage. All relevant parts of the overall process "intelligent grid" are modeled into the world of discrete event simulation and first implementation results are discussed.

“…The issues of note consist of voltage violations, loss impacts, power quality effects, protection considerations, and reliability concerns [1]. The key limiting factor in large scale DG integration, however, remains the voltage-rise effect on network buses [2]. In order to minimize the overall effect on voltage, network operators prefer to connect DGs at higher voltages where their impact on voltage levels is negligible; but as connection costs increase considerably at higher voltages, developers tend to prefer to connect their equipment at lower voltages, i.e.…”

Abstract-This paper considers the effects of various voltage control solutions on facilitating an increase in allowable levels of distributed generation installation before voltage violations occur. In particular, the voltage control solution that is focused on is the implementation of 'soft' normally-open points (SNOPs), a term which refers to power electronic devices installed in place of a normally-open point in a medium-voltage distribution network which allows for control of real and reactive power flows between each end point of its installation sites. While other benefits of SNOP installation are discussed, the intent of this paper is to determine whether SNOPs are a viable alternative to other voltage control strategies for this particular application. As such, the SNOPs ability to affect the voltage profile along feeders within a distribution system is focused on with other voltage control options used for comparative purposes. Results from studies on multiple network models with varying topologies are presented and a case study which considers economic benefits of increasing feasible DG penetration is also given.
