AEE Project Work course 2019 Master’s Programme in Automation and Electrical Engineering Jakov Chavez Vega (project manager), Joonas Hurtta, Henri Selenius, Kalle Valtavirta, Bahman Eskandari (instructor) A multi-purpose platform of a Grid Connected Converter (GCC) Objective Share of renewable energy sources (RES) is increasing and its intermittent nature causes problems in grid stability. Current storage and converter technologies are not suitable for large increase in variable RES. The objective of the project was to implement a multipurpose platform of a grid connected converter bearing in mind the target customers: researchers, students and other interested parties. The objective was to make an off-the-shelf type of product, that is very adaptable, can be used in several different high voltage applications and can be controlled easily by any user from the MATLAB environment. A short delivery time and access for all interested parties is an important aspect. The total market size of GCCs is already over 5 billion euros with strong existing players, and the market is growing fast with new players entering. The target market share is 1% of the total market. The features of a traditional and a multifunction GCC Implementation of the grid connected converter before the final packaging solution The work breakdown structure of the project Results The grid connected converter prototype was built successfully. The controller in the MATLAB environment works properly and the GCC works as it was planned to work with the application chosen for it. The operational GCC also meets the international standards and it was tested in high voltage laboratory, where it worked correctly. Multi-purpose capability of our converter enables the connection between different storage systems and the GCC. The converter can also be used for any kind of power source of different capacities or various types, and it enables a connection to electric vehicles. All of these functions are theoretically possible, but need more accurate testing first. The other benefits are that the customer can buy our multipurpose converter and be sure that it is compatible with the selected application, which means financial savings for customers and a peace of mind. It is easy for customers to control the converter by using Simulink which provides a flexible testing platform. The production cost of one GCC is approximately 1000 -1500 € including all parts and design costs. The product is a relatively cheap and an available platform for researchers, students and other interested parties.
