  • Control systems for hybrid solutions based on biomass fueled Stirling engines, solar and wind for rural electrification

    The project is part of a program for solutions to rural electrification in Bolivia. I study the control system for a Hybrid power system based on a wood pellet fueled Stirling engine. This system has to be capable to operate on islanded mode in rough rural conditions. In addition, the system harvest the local energy sources to assure the reliability of the system.

  • Towards Sustainable (Fossil-free) Heating System in Small Residential Buildings

    As a growing technology, the number of installed heat pumps in Europe was increased by 60% between 2014 and 2018, and European Heat Pump Association expects a doubling in the heat pump market by 2024. It is therefore a high priority to further increase the share of renewable sources in the heat pump’s configuration to increase the potential of energy savings and to reduce the greenhouse gas emission. The goal of this project is to study the performance of the PVT-assisted GSHP in new- and retrofitted single-family houses.

  • Prosumer-Centric Communication for Solar PV Diffusion (completed)

    Numerous environmental threats are motivating the transition to a sustainable energy system. Buildings are a major contributor in that they represent 39% of final energy consumption in Sweden while simultaneously providing a great potential for solar photovoltaics (PV). To adopt PV, building owners must navigate a complex landscape of technology options, suppliers, and economic uncertainties, challenging their decision making process.

  • Solar energy and ground source heat pumps for Swedish multi-family housing (completed)

    Ground source heat pumps (GSHP) have a relatively small market share in multi-family houses in part due to the limited land space available for drilling. The rapidly growing market for solar photovoltaics (PV) provides an opportunity for GSHP by acting as a secondary heat source and regenerating the ground via a heat exchanger fixed to the rear of the panel. The hybrid PV/thermal collectors, called PVT, have higher efficiencies than PV only, but also come with a significant additional cost.
