A real-time controller concept demonstration for distributed generation interconnection

Abstract

In this paper, the set up and demonstration of a real-time controller based on the IEEE Std. 1547 for interconnection of distributed generation (DG) sources to the electric utility grid is presented. The case studies described are based on the philosophy of real-time (RT) hardware in the loop (HIL) simulation. The RT-HIL technique is capable of providing insight into the performance of both the system with the DG as well as the external hardware controller. The results of a real-time controller concept demonstration may be useful in understanding the recommendations of the IEEE Std. 1547 and analyzing the system impact of the interconnection of DGs.

An Advanced Platform for Development and Evaluation of Grid Interconnection Systems Using Hardware-in-the-Loop: Part III -- Grid Interconnection System Evaluator

“…Many other projects have leveraged CHIL and PHIL techniques for use with motor drives [9], generator excitation systems [10], and renewable energy applications [11] [12]. The use of HIL for grid conformance testing is mentioned in [13] and [14], however both of these works simply mention concepts and methodologies for testing different grid conformance aspects and lack implementation and results. In the case of the GISE described in this report, HIL simulation techniques are used to considerably shorten the amount of time required to complete a full set of grid interconnection conformance tests by placing a software control model of each conformance test in the loop with the ICS under test and the related electrical test equipment.…”

Accelerating the customer-driven microgrid through real-time digital simulation

“…The Thunderstone system, developed and tested in [6], was chosen as a suitable candidate for CDM testing and evaluation. A summary of this electrical power system model that was implemented on a RTDS, is illustrated in Fig.…”

Low-cost real-time monitoring of a laboratory scale power system

“…These cases are divided to: a) controller HIL and b) power HIL methods. For the controller HIL [2], [7], the power system and the power converter (e.g., a machine or a power electronic converter) is real-time simulated using RTDS and the controller of the power converter is developed using real-time controller boards [3]- [5] in order to test the controller of the power converter. On the other hand, in case of power HIL [2], [8], the power system operation is realtime simulated using RTDS equipment, while the power converter among with its controller is tested as an experimental hardware prototype.…”
