Smart Grid Simulation in MATLAB

Smart grid Simulation in MATLAB

MATLABSolutions demonstrate how to use the MATLAB software for simulation of a smart grid. The smart grid is the integration of computing and communication technologies into a power grid with the goal of enabling real-time control and a reliable, secure, and efficient energy system. With gained interest of the research community and stakeholders towards the smart grid, a number of solutions and algorithms have been developed and proposed to address issues related to smart grid operations and functions. These technological problem solutions need to be tested and validated before implementation using software simulators.

Thus we developed a general smart grid simulation model in the MATLAB/Simulink environment, which integrates energy storage technology, load monitoring, and control capability. To show the validation of effectiveness of our simulation model, we created simulation scenarios and performed simulations using a real-world data set.

Abstract

Smart grid systems are characterized by high complexity due to interactions between a traditional passive network and active power electronic components, coupled using communication links. Additionally, automation and information technology plays an important role in order to operate and optimize such cyber-physical energy systems with a high(er) penetration of fluctuating renewable generation and controllable loads. As a result of these developments the validation on the system level becomes much more important during the whole engineering and deployment process, today. In earlier development stages and for larger system configurations laboratory-based testing is not always an option. Due to recent developments, simulation-based approaches are now an appropriate tool to support the development, implementation, and rollout of smart grid solutions. This paper discusses the current state of simulation-based approaches and outlines the necessary future research and development directions in the domain of power and energy systems.

A Virtual Smart Grid

It is typically identified that a high-bandwidth and fairly to be had networked conversation gadget need to overlay the transmission system topology on the way to permit the manage and safety envisaged today to make the grid greater efficient and greater reliable. The specifications for this type of communique gadget had been tough to broaden, but, as it needs to guide a wonderful style of packages, lots of which have now not but been developed. Organizations including the North American SynchroPhasor Initiative (NASPI) are looking to build in this vision of a communique device which could make use of phasor dimension statistics to initiate fast controllers, inclusive of flexible alternating present day transmission gadget (FACTS) gadgets.

A major hurdle in developing such fast, extensive area controls has been the shortage of design gear available to do so. In precise, the improvement of controls that rely on communications to hold the input and output signals and complex software to manner those indicators requires gear to simulate and analyze such controls. To accurately painting the conduct of such controls, layout gear need to integrate the dynamic conduct of the energy device with the reaction of the conversation and computation system.

We describe here a simulator—GridSim—that can simulate in real time the electromechanical dynamic behavior of the power grid, the IT infrastructure that overlays the grid, and the control systems taking advantage of that IT infrastructure. This simulator was devised for designing and testing new wide area control and protection schemes. GridSim is able to represent a large portion of a grid and runs in real time so that various components running at different sampling rates can be tested together.
