Cost Benefit and Situation Analysis Method of Premium Power

As a typical power quality problem, voltage sag will affect the power experience of important power users. Controlling voltage sag is one of the shortcuts for important power users to obtain premium power. This paper starts from the public power grid level, user power grid level and electrical equipment level, studies the premium power measures at all levels, constructs the corresponding cost benefit quantitative model, and analyzes the strengths, weaknesses, opportunities and threats of implementing premium power measures at all levels based on SWOT method, providing important reference for the subsequent design of premium power services.
