Offer Description

Tallinn University of Technology School of Engineering, Department of Electrical Power Engineering and Mechatronics offers a 4-year PhD position in electrical power engineering and mechatronics.

The proposed PhD thesis topic: "New Methodology for Distribution Grid Planning Considering Impact of Power Flow Pattern Changes on Coincidence Factor"

Supervisors: Tenured Full Professor Argo Rosin and Researcher Vahur Maask (TalTech)

Abstract
The overall goal of the project is to research and develop a new methodology for low voltage distribution grid planning considering the impact of power generation and consumption pattern changes on coincidence factor. The long-term strategy of the European Union is aiming at climate neutrality to be achieved by 2050 poses serious challenges to all branches of the economy, incl. the energy sector. It is expected that 50% of the supplementary renewable energy sources will be connected to the distribution network, of which 25...50% are direct current solutions added to the network through power electronics. The increasing sporadic nature of power generation and consumption and frequent changes in power flows constitute a challenge to the electric power system in several aspects: quality of electricity, supply chain security, reliability of network components, network losses as well as unpredictable end-user price fluctuations etc.

Description
The goal of the PhD project is to develop an innovative approach for planning distribution grids that consider the impact of changing power flow patterns on coincidence factors. By doing so, the project aims to enhance the efficiency, reliability, and sustainability of electricity distribution systems. The specific objectives include creating a new planning methodology, analyzing its effectiveness, and assessing its economic implications. Ultimately, this research contributes to better grid management and resource allocation in the face of evolving energy demands and generation profiles.

PhD project should address several key research questions to advance our understanding and improve distribution grid planning. Here are some relevant questions:

How do changes in power flow patterns impact coincidence factors in distribution grids?

What are the limitations of existing distribution grid planning methodologies in accommodating dynamic power flow patterns?

How can the proposed methodology proactively incorporate the capabilities of Distributed Energy Resources (DER) into grid planning and operation?

What data sources and information from current smart grids can be effectively utilized to enhance distribution grid planning?

What are the potential operational services that can optimize network capacity utilization at the distribution level?

How does the new methodology compare to traditional approaches in terms of cost-effectiveness, reliability, and sustainability?

What are the socio-economic implications of implementing the proposed distribution grid planning methodology?

Research tasks would involve a combination of quantitative and qualitative research methods, including data collection through surveys, simulations, and possibly field studies, followed by data analysis using statistical and computational techniques. The goal would be to enhance the efficiency, reliability, and sustainability of electricity distribution in the face of evolving energy demands and generation profiles.

Responsibilities and (foreseen) tasks

• Developing a new methodology for distribution grid planning that can adapt to changes in power flow patterns. Investigate the international and national regulations which could induce developments affecting the coincidence factor in low voltage distribution grid. State of Art study previous scientific studies related PhD thesis topic
• Analyzing the impact of these power flow pattern changes on coincidence factors, which are crucial for understanding peak demand and resource allocation. Analyze large-scale data from smart meters, IoT devices, and distributed energy resources to develop models for coincidence factor studies. Develop new scenarios for determination of coincidence factor for different low voltage grid areas, e.g. distributed, mid-dense, dense and super-dense areas simulations
• Creating models in DigSILENT to predict and simulate how different scenarios affect the distribution grid
• Evaluating the effectiveness of the new planning methodology against current practices. Determine the impact of distribution network changes on the coincidence factor due to the addition of solar parks, EVs, energy storages and aggregated loads using the DigSILENT software
• Assessing the scalability of the proposed methodology for different sizes and types of distribution grids.
• Investigating the economic implications of the methodology, including cost-benefit analysis.
• Ensuring compliance with regulatory standards and environmental considerations.
