Analysis of Economic Factors Affecting Power Supply Planning in Off-Grid Systems

Off-grid power systems are an effective solution to meet the electricity demands of remote, off-grid areas. This paper analyzes the economic factors influencing off-grid power systems, identifying key and non-key factors in power planning costs. Based on this analysis, the most economically optimal power capacity configuration is selected to achieve cost control of the system. First, an analysis of the factors affecting the operational revenue and operational costs of off-grid systems is conducted to identify the key factors influencing economic performance. Then, the factors affecting the economic viability of the power supply system are derived through differential analysis, and the key influence of each factor on revenue and cost is quantified by calculating the impact factors. Finally, the effects of different influencing factors on the system's economy are assessed based on the magnitude of their respective factor coefficients. This research provides a theoretical basis for achieving the optimal economic planning of off-grid power systems.
