摘要

可再生能源发电系统的可靠性评估是一个复杂的问题，特别是风电和光伏发电具有间歇性和时变的特点。为了简化计算负担，通常采用等效强制停运率的概念。提出了一种多状态模型来表示可再生能源的可变发电。通过考虑电厂因素，可以简化降级状态数和相应的降级容量。它声称，一些特定的容量状态可以被忽略。发电系统的可靠性可以用两个经典指标来评估:负荷损失概率和期望无供能。

An approximated multi-state model for reliability evaluation of renewable generation

Reliability evaluation of power generation system is complicated with the integration of renewable sources, especially wind turbine and photovoltaics, whose generation characteristics are intermittent and time-varying. The concept of equivalent forced outage rate is conventionally utilized to simplify the computation burden. It is proposed to apply a multi-state model to express the variable generation of renewable sources. Number of de-rated states and corresponding de-rated capacities can be simplified by considering the plant factor. It is claimed that a number of certain capacity states may be neglected. Generation system reliability may be evaluated using two classical indices: loss of load probability and expected energy not supplied.
