Probability of adequacy evaluation considering power output correlation of renewable generators in Smart Grids

This paper presents a new analytical expression useful to assess the ability of local DGs to meet a potential island load. Such an expression accounts for both load shedding and curtailment policies and it encompasses the correlation among loads' power demand, the correlation among renewable DGs' power outputs for generators of the same technology, the correlation among renewable DGs' power outputs for generators of different technologies, and, finally, the correlation among loads' power demands and renewable DGs' power outputs.
