✔ Safety: This concept can be further subdivided into two major classes, as shown in figure 3. customer safety means making the network safe; it depends on issues such as insulation limits. ✔ Quality: This concept is known in the power industry as power quality and is broken into three major categories, which are shown in figure 3. By causing voltage drop, transient mode makes problems for customers and decreases their performance and efficiency. nonstandard voltage and harmonics also decreases the operational quality of consuming devices. ✔ Stability: This concept is known as reliability. Distribution company reports, such as asset management and network planning reports, mostly emphasize providing high reliability for customers. reliability planning for distribution companies has been considered in various studies.
