Benefit-Cost Analysis for Private PV System Investment with DSTATCOM Compensation

摘要

This paper presents a benefit-cost analysis for private photovoltaic (PV) system investment with distribution static compensator (DSTATCOM) compensation to enhance the PV penetration in distribution systems. A hybrid voltage control scheme with reactive power compensation from DSTATCOMs and active power curtailment is applied to avoid the violation of voltage variation caused by large PV power injection. The PV power generation is estimated based on local solar irradiation and temperature data. The annual curve of PV power generation and annual energy delivered to the distribution system with the hybrid voltage control scheme are also determined. The annual revenue of PV power sales, the initial capital investment cost of a PV system with or without a DSTATCOM, and the operating and maintenance cost are then considered to evaluate the benefit and cost of the PV investment over its life cycle.
