摘要
Abstract
Electricity price is a key factor affecting economic benefit of family grid-connected photovoltaic (PV) systems.Concerning two mainstream power purchase policies as time-of-use tariff and ladder tariff,an optimal operation scheduling problem is formulated with consideration of electricity income,electricity cost,government subsidy and other factors.Dispatching ratio of PV power system output is taken as optimization variable while user's benefit is formulated as maximized objective.Corresponding constraints of optimization problems are also analyzed.A genetic algorithm is proposed to solve above problems.Finally,a typical family grid-connected photovoltaic system is taken as study case,where optimal operation instructions under two tariff systems are obtained.Convincing results are presented to validate the models and optimal operation strategies.关键词
