This project aims to propose a commercial smart energy management systems prototype based on supervisory control and data acquisition systems to monitor and control local generation and consumption.
Buildings (residential and commercial) are the main sector in terms of energy consumption (around 40%). Hence, activating smart energy management systems (EMS), including electricity, heating, and cooling systems as flexible and responsive actors in electrical and thermal grids is vital to integrate intermittent renewable energy sources (RESs) and energy storage systems (ESSs).
A Commercial Smart EMS Prototype
This project aims to propose a commercial smart EMS prototype based on supervisory control and data acquisition (SCADA) system to monitor and control both local generation and consumption. The SCADA will be used in a multi-energy carrier system including electricity, heating, and cooling in a real energy hub called HelioS to enhance local energy flexibility as well as self-consumption. To achieve this, an optimal battery energy storage system (BESS), as the key component, needs to be sized to provide a reliable source of power and energy for peak shaving, hosting electric vehicles (EVs), providing local energy flexibility and consequently cost saving.
The specific goals of the Helios energy hub project include:
- HelioS energy hub capacity evaluation to handle variations in local generation and demand.
- Identifying the cost-optimal solution for a given business energy hub application.
- An optimal BESS size in HelioS energy hub for local energy flexibility and self-consumption purposes.
- A real-time EMS based on SCADA system to monitor HelioS energy hub for laboratory and research applications.
The solar cell production at the University of Skövde
HelioS energy hub, with a remarkable power demand and Photovoltaic (PV) production power (around 200 kWp) at University of Skövde, aims to maximize self-consumption and minimize grid taxes. The solution is to optimally size a BESS considering the system constraints, e.g., uncertainties, load demand variation, and energy price market with a real-time EMS for local energy flexibility and saving purposes.
The smart EMS which is one of the main parts of the prototype involves SCADA system as well as intelligence methods to provide real-time communication between different parts of the system, e.g., PV system, BESS, heat pump, electric chiller, heating and cooling storages to improve efficiency and providing local energy flexibility and maximize self-consumption. In details, HelioS energy hub project covers some issues from economic, technical, and environmental areas.
However, the project outcomes could be highlighted in two target groups:
- Helios energy hub target 1: A holistic techno-economic solution for a given business model for energy flexibility and saving purposes.
- Helios energy hub target 2: A real-time EMS based on the SCADA system to monitor HelioS energy hub operation for laboratory and research applications.
