Description The thesis student will work on the PVZEN project (PV Zero Energy Network), an experimental laboratory for energy communities installed within the Polytechnic University of Turin. PVZEN includes photovoltaic generation systems, lithium battery systems, and loads capable of exchanging power according to control strategies defined by a centralized control unit. The purpose of PVZEN is to test energy exchange strategies aimed at maximizing the use of renewable energy sources, particularly photovoltaic systems supported by electrochemical energy storage systems.

The thesis work will be structured as follows:

- **Chapter 1:** Analysis of current Italian regulations regarding voltage control from renewable energy sources (LITERATURE REVIEW).

- **Chapter 2:** Literature review of power management and reactive power optimization strategies in wind farms for voltage regulation at the grid connection point (LITERATURE REVIEW IN SCIENTIFIC LITERATURE).
*Objective:* To explore how reactive power flows are managed within wind farms according to existing scientific literature.

- **Chapter 3:** Selection and application of management strategies to the real-world case of the wind farm under examination, with optimization aimed at minimizing Joule losses.
The thesis student will develop a MATLAB program for managing reactive power profiles based on active power monitoring. The student will interface with an existing control program, which must be customized according to the new strategies. Once completed, the program will be deployed in the real PVZEN system. The student will monitor its operation, calculate performance, verify the absence of errors, and compare results with those obtained using other strategies. This chapter will detail the entire process (MATLAB SIMULATION).

- **Chapter 4:** Analysis and comparison of the results obtained from the work described in the previous chapter (SIMULATION AND ANALYSIS).

- **Chapter 5:** Conclusions.

Required skills -linguaggio di programmazione MATLAB
-conoscenza teorica del power flow trifase squilibrato (corso Prof. Chicco - Distribuzione e utilizzazione dell'energia elettrica)



Notes il tempo medio per l'attività di tesi è di 6 mesi, ma dipende dall'impegno del tesista. Il tesista potrà laurearsi quando il lavoro di tesi, concordato a priori, sarà completo, così come la scrittura adeguata del documento di tesi.
