Griffith University’s promising battery energy storage system

Battery energy storage project shows promise for electricity network, Eureka Alert 2 Apr 15  Cheaper, more efficient power among benefits from intelligent scheduling and operation system GRIFFITH UNIVERSITY WITH RISING ELECTRICITY PRICES ONE OF THE BIGGEST ISSUES FACING HOUSEHOLDS, GRIFFITH UNIVERSITY (AUSTRALIA) RESEARCH INTO ENERGY STORAGE AND SUPPLY HOLDS THE PROMISE OF CHEAPER, BETTER QUALITY POWER FOR THE LOW VOLTAGE (LV) ELECTRICITY DISTRIBUTION NETWORK.

According to the research from Griffith’s School of Engineering and published in the journal Applied Energy, a forecast-based, three-phase battery energy storage scheduling and operation system provides benefits such as reduced peak demand, more efficient load balancing and better management of supply from solar photovoltaics (PV).

Researcher Mr Chris Bennett, working under the supervision of Associate Professor Rodney Stewart and Professor Jun Wei Lu, has developed and applied an intelligent scheduling system to a South-East Queensland-based LV distribution network servicing 128 residential customers.

“The low voltage network is a typical suburb of a few hundred homes where there is a single area transformer and recently there has been a substantial increase in the number of homes with installed residential solar PV in these settings,” says Mr Bennett.

“Daily peak demand in residential networks typically occurs in the evenings in summer and both late morning and evening in winter. But because solar PV generation is dependent on incoming solar radiation, peak generation occurs during the middle of the day, typically when demand in the residential distribution network is low.”

“This means there is an incongruity between when energy is generated and when it is required, which can lead to power supply and quality issues.

“However, with a battery energy storage (BES) system comprising Lithium Ion battery banks coupled with smart power control systems, such as STATCOMS, and featuring embedded intelligent forecasting software, we can better manage the LV network.”……..
