AC Micro Grid Flexible Simulation Utility for SCADA System Development

摘要

Nowadays, it is a common practice to utilize supervisory control and data acquisition (SCADA) based system for centralized power flow management and control of all scales of power systems. That ranges from national wide common utility to small isolated micro-grid. However, the software development cycle including design, deployment, debugging and test is rather complicated due to the numerous situations that might occur as well as the large number of input/output involved. This paper presents a flexible software utility that can be reconfigured to simulate wide range of AC micro-grid configurations and operation scenarios. The utility is designed using object oriented programming paradigm, and implemented using C++programming language. The design allows for providing simulation results for SCADA platform in real-time. It allows multi-level of modeling and numerical solution. In this paper, the RungeKutta and Newton-Raphson methods are combined to simulate different scenarios of AC micro-grid operation. The consistency of results and efficiency of dynamic simulation indicates the effectiveness of proposed utility.
