摘要：In this paper, we study an electricity load scheduling problem in a household with PV system according to the relationship of size between the Feed in Tariff(FIT) tariffs and time-of-use(TOU) pricing. Compared with previous works in which PV energy is either fully consumed by customers or fully exported to the main grid due to smaller or larger FIT than electricity price, we consider the PV energy is partially consumed by customers or exported to the main grid. Two customer's gains equations for using of PV energy are established, one is for PV energy exported to the main grid and the other is for PV energy consumed by customers. With these equations, we develop a mathematical model with condition of inequalities for unknown power direction between the customer and the main grid in order to maximize the customer's gains. In order to solve the proposed model with condition of inequalities, we transform the proposed model into a Mixed Integer Linear Programming(MILP) model by introducing auxiliary variables and linear expression technologies for product of binaries variable and product of a binary variable and a bounded continuous variable. Numerical results show that our proposed scheme can effectively increase the customer's gains and satisfy the utility's load reduction request.
