Abstract: |
Currently, small islands are facing an energy
supply shortage, which has led to considerable concern.
Establishing an island microgrid is a relatively good solution
to the problem. However, high investment costs
restrict its application. In this paper, micro pumped storage
(MPS) is used as an energy storage system (ESS) for
islands with good geographical conditions, and deferrable
appliance is treated as the virtual power source which can
be used in the planning and operational processes.
Household acceptance of demand response (DR) is indicated
by the demand response participation degree
(DRPD), and a sizing optimization model for considering
the demand response of household appliances in an island
microgrid is proposed. The particle swarm optimization
(PSO) is used to obtain the optimal sizing of all major
devices. In addition, the battery storage (BS) scheme is
used as the control group. The results of case studies
demonstrate that the proposed method is effective, and the
DR of deferrable appliances and the application of MPS
can significantly reduce island microgrid investment.
Sensitivity analysis on the total load of the island and the
water head of the MPS are conducted. |
