The invention discloses a micro-
grid system capacity optimal configuration method based on a fan-shaped
radar map model. The method comprises the following steps: firstly, selecting a load power lossrate, an annual cost, a
renewable energy power
generation loss rate and an energy excess rate as evaluation indexes in four aspects of
microgrid system power supply stability, economy, a
new energy consumption condition and an energy
utilization rate, establishing a fan-shaped
radar map model, and setting the area of a fan-shaped
radar map as an objective function; taking the maximum area of the fan-shaped radar map as a target, obeying constraint conditions, and establishing an optimization
mathematical model of micro-
grid system capacity configuration; finally, a
genetic algorithm based on aload tracking
management strategy is adopted; solving an optimal configuration scheme of the micro-
grid system capacity; the
correctness and feasibility of the optimization method are verified through actual examples, the optimization configuration scheme can meet the stable operation target of the
microgrid system composed of various
new energy modules and
energy storage devices, and economic operation of the
microgrid system and efficient utilization of
renewable energy sources are facilitated.
