Frequently Asked Questions

What is the primary focus of this work?

The work primarily focuses on addressing poor power quality and stability issues in Kosovo’s electrical distribution network, using northern Prishtina as a case study to demonstrate technical and managerial improvements.

What are the central themes of the research?

Central themes include technical loss reduction, infrastructure modernization, the transition to higher voltage levels (20kV), and the implementation of efficient project management strategies.

What is the core objective of the project?

The primary objective is to upgrade the existing design of the distribution network to achieve higher reliability, reduce technical losses, and ensure that electrical energy supply meets modern quality standards.

Which scientific methods were employed?

The research employs network simulation using Gredos and Power Factory software, combined with field data collection, SWOT analysis for risk management, and cost-benefit analysis based on technical loss reduction.

What is covered in the main section of the book?

The main section covers a detailed assessment of existing network conditions, proposed technical design solutions (such as conductor upgrades and transformer changes), and the management framework required for project implementation.

What keywords characterize the research?

Key terms include Distribution Network, Power Quality, Technical Losses, Grid Stability, Infrastructure Upgrades, and Project Management.

Why was Northern Prishtina chosen as the study area?

It was chosen because the existing substation (Prishtina 5) has the capability to support the necessary 110/20kV transformation, and the region exhibits a mix of urban and rural network challenges, making it an ideal pilot for transition.

What role does the transition from 10kV to 20kV play?

It is presented as the most effective solution for significantly reducing technical losses and voltage drops in the middle voltage network, allowing a large portion of existing equipment to function more efficiently.

How are project risks addressed?

Risks are addressed through a structured SWOT analysis, identifying internal strengths and weaknesses and external opportunities and threats, followed by management plans to mitigate identified bottlenecks and financial constraints.
