1. Increasing the hosting capacity of distributed energy resources using storage and communication
Sammanfattning : The use of electricity from Distributed Energy Resources like wind and solar powerwill impact the performance of the electricity network and this sets a limit to theamount of such renewables that can be connected. Investment in energy storage andcommunication technologies enables more renewables by operating the networkcloser to its limits. LÄS MER
2. Increasing the hosting capacity of distributed energy resources using storage and communication
Sammanfattning : This thesis develops methods to increase the amount of renewable energy sources that can be integrated into a power grid. The assessed methods include i) dynamic real-time assessment to enable the grid to be operated closer to its design limits; ii) energy storage and iii) coordinated control of distributed production units.

3. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants
Sammanfattning : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.

4. Weekly planning of hydropower in systems with large volumes of varying power generation
Sammanfattning : Hydropower is the world’s largest source of renewable electricity generation. Hydropower plants with reservoirs provide flexibility to the power systems. LÄS MER
5. Renewables Based Polygeneration for Rural Development in Bangladesh
Sammanfattning : Despite the country's rural electrification programme, kerosene is the predominant source for lighting, and unsustainable and polluting woody biomass is virtually the only option available for cooking. The rural population also struggles with unsafe drinking water in terms of widespread arsenic contamination of well water. LÄS MER
