# Electricity Losses in Focus: Detection and Reduction Strategies--State of the Art
## 6 Conclusions  
This study presents a comprehensive review of the extant literature on the primary categories of power losses that occur in electricity networks. The identification of these losses is a multifaceted and significant process, as they have a direct impact on the stability of power grids and the quality of electricity. A comprehensive review of the extant literature has been conducted, addressing methodologies employed for the identification and reducing of these losses. The objective of this review is to contribute to the enhancement of electricity supply. Consequently, this paper presents a systematic prioritization of scientific works and research conducted in the energy sector, categorized according to the categories of energy losses. The conclusions related to this review highlight the importance of studying energy losses in power systems globally. Therefore, different aspects have been analyzed within each section of the report, each exemplifying the importance of an accurate treatment of the contributions and challenges of this field. Section 1, for example, addresses a critical area in terms of the functionality of an electro-energy system, highlighting the main phenomena, such as the generation, transmission, distribution, and use of electricity. This section describes the main methods for calculating technical losses and introduces a series of explanations of the processes that cause these losses. Section 2 presents, in detail, the typologies of electricity losses that occur in electricity networks, such as losses due to physical components in the system, losses generated by measurement and accounting errors, energy theft, etc. These are analyzed separately to provide an overview of the overall contributions of this paper. The subsequent section, Section 3, emphasizes the detection methods employed for the two primary categories of energy losses: technical losses and non-technical losses. These detection methods have been studied and implemented to a certain extent, yielding encouraging results. Furthermore, these methods have undergone further development and study following their implementation. Furthermore, Section 4 offers a comprehensive review of both conventional and novel methodologies for minimizing these primary loss categories. This section accentuates a technologically sophisticated process that integrates artificial intelligence technologies, ensuring precision and complexity in the outcomes. Finally, Section 5 discusses the primary challenges and obstacles encountered in implementing energy loss detection and reduction methods in energy systems, emphasizing the analysis of pertinent literature in a systematic manner. In conclusion, an analysis of technical and non-technical energy losses in power networks reveals a substantial problem of high complexity, which is essential for increasing energy efficiency while simultaneously promoting the sustainability of electricity transmission and distribution systems. The occurrence of technical losses is an unavoidable process primarily caused by limited physical and technological infrastructure. However, these losses can be mitigated through measures such as upgrading and reconfiguring power grids or integrating advanced smart technologies to optimize consumer supply operations according to their unique consumption profiles. Conversely, non-technical energy losses
