Microgrid Pre-dispatch Considering Battery Low-temperature Characteristics

Abstract

The use of storage batteries helps to reduce peak load and improve microgrid economics. Its safe and steady operation is critical for the microgrid’s proper dispatching of distributed power generation. However, the battery’s available capacity and charge-discharge efficiency are considerably lowered at low temperatures. It will be difficult to calculate the energy storage system’s daily operation cost accurately, and batteries will risk overcharging without considering battery’s low-temperature characteristics in microgrid pre-dispatch. This paper proposes a microgrid pre-dispatch model considering battery low-temperature characteristics. The case study demonstrates that the suggested method has a good optimization effect by enhancing the dispatching scheme’s security and economy.
