The Use of Energy Storage to Improve Controllability and Security of the Belarusian Power System
Keywords:Energy system, nuclear power, energy storage system, daily load schedule
The planned commissioning of the second unit of the Astravets nuclear power plant in the Republic of Belarus in 2023 will exacerbate the need to ensure controllability and security of both the entire Belarusian power system and its individual power generation centers. To address this issue effectively, it is crucial to flatten the load curves of electricity consumers, and energy storage systems (ESS) make this achievable. The Belarusian power system can use several types of ESSs, both system-wide and local. Li-ion-based ESSs have the best performance when used to smooth the load curves of individual substations. This paper assesses the efficiency of lithium-ion energy storage units. The assessment focuses on various factors such as leveling of the daily load curve of the consumer, decrease in power loss, and voltage regulation at the ESS installation site.
