Due to highly volatile feed-in by renewable energy sources (RES), a large amount of potential controls in future smart grids as well as the striving for gains in efficiency, power system operation becomes increasingly complex. This complexity is a particular challenge for real-time operation as centralized optimizations of the non-linear system are computationally intensive and rely on adequate data sets. The application of distributed control systems as a complement or substitute for certain centralized control decisions offers advantages regarding adaptiveness, robustness and real-time performance. In this paper, the progress on developing a distributed coordination system for power flow control by HVDC links and AC power flow controllers is presented. Currently, the coordination of power flow controllers is performed manually from a control center based on time-consuming centralized calculations. Due to its decentralized structure, the proposed coordination system enables a robust real-time response. This benefits operational security as counteractions can be initiated immediately in case of unforeseen events and enables the allocation of more transmission capacity in congested network areas.

Monitoring, Control and Protection of Interconnected Power Systems

In the previous chapters, newly designed applications from the field of Wide Area Monitoring, Protection and Control (WAMPAC) systems have been introduced and results have been presented for individual applications. However, it is of particular importance to evaluate these applications in interaction in order to analyze their joint performance and their interdependencies. Furthermore, power systems become more and more dependent on Information and Communication Technologies (ICT) for information exchange and data processing at local (intrasubstation) and remote (inter-substation/control center) levels. Especially timecritical WAMPAC applications require powerful and reliable ICT systems. Consequently, the real-time performance of these applications needs to be evaluated in detail taking into account the ICT system. Simulations are a common way for analyzing the suitability of new approaches for power and ICT systems, but as both networks are highly interdependent and mutual effects can occur, simulations need to address two aspects comprehensively: electromechanical effects modeled within a power systems simulation and communicative effects modeled within a communication networks simulator.In this chapter, we present a hybrid simulation architecture that enables the comprehensive analysis of the interplay of monitoring, protection and control applications taking into account both power and ICT systems. The co-simulation framework is based on the IEEE 1516-High-Level Architecture (HLA) and is currently under development in DFG research unit FOR1511.

“…These make it possible to respond in real-time to contingencies, thus contributing to system stability, and to gain the economic benefits by dynamic power flow control for transmission corridors. [6] Prior to the introduction of real-time phasor measurements power system control was essentially local. The introduction of phasor measurements offers the possibility of control based on measurement value of remote quantities.…”

Synchrophasors (Synchronized phasor measurements) provide a new method for enhanced visualization of system conditions and can lead to new kinds of adaptive WideArea protection, emergency control, and optimization systems. Through the use of synchrophasors, simple values such as voltage angles, line flows, and breaker statuses, can be viewed in real time rather than delayed by scan rates and calculations.Advanced quantities, such as oscillatory modes, damping ratios, and local time errors, can be calculated and displayed in order to be used by operators.The introduction of synchronized phasor measurements in protection, control, and automation devices has greatly improved the observability of power system dynamics.
