The Assessment of Distributed Photovoltaic Capacity Credit in Courts Considering High Penetration

Abstract

Due to the intermittent and volatility of photovoltaic power generation, it is generally considered that there is only electricity value and no capacity value. With the high penetration of large-scale distributed photovoltaic access to low-voltage distribution network, distributed photovoltaic will gradually become an important alternative energy source. Based on the theory and experience of domestic and international photovoltaic power generation capacity credit assessment, this paper studies the correlation between distributed photovoltaic season, diurnal power generation characteristics and load. This paper also studies the characteristics of power generation system and characteristics of the power distribution system under high penetration distributed photovoltaic access. A calculation method for the capacity credit of high penetration in multi-scenario courts is proposed to provide support for precision investment.
