Title:
MICROGRID CONFIGURATION OPTIMIZATION METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/183580
Kind Code:
A1
Abstract:
The present invention provides a microgrid configuration optimization method, the method comprising: determining the net output power of renewable energy, and determining an electricity supply mode of a microgrid according to the net output power of the renewable energy, wherein the electricity supply mode at least comprises: a mode of supplying electricity only by means of the renewable energy, a mode of supplying electricity jointly by means of the renewable energy and a large power grid or an energy storage apparatus, and a mode of supplying electricity only by means of the large power grid. After the electricity supply mode of the microgrid is determined, the net output power of the renewable energy at a subsequent moment also needs to be determined, so as to update or maintain the electricity supply mode of the microgrid. Since distributed renewable energy of a microgrid is characterized by intermittency and randomness, the process of electricity supply is instable. The electricity supply mode of a microgrid can be switched in a timely manner by means of determining the net output power of renewable energy, thereby ensuring electricity supply stability of the microgrid; and other energy is utilized in a timely manner when electricity supplied by the renewable energy is insufficient, which also ensures full utilization of the energy inside the microgrid.
