RatedPower adds AC-coupled storage support to utility-scale solar design software

Rated power has integrated a new feature into its design software pvDesign that hybridizes PV installations via AC-coupled battery and energy storage system support.

“We are excited to release the basic engineering of an AC-coupled BESS that will become a fundamental part of our entire business strategy. This new feature of pvDesign is the first step in providing our customers with a complete hybrid PV-BESS solution,” said Ignacio Álvarez, Product Manager at RatedPower.

IRENA estimates that the deployment of large-scale storage systems in energy markets will increase by 40% each year until 2025. Battery energy storage systems are attractive at this scale because:

They are a solution to overcome the obstacles caused by the intermittent production of renewable energy.

BESS contributes to providing reliable and cheaper electricity in isolated grids and off-grid communities that would otherwise depend on expensive and polluting fossil fuels such as diesel.

According to Bloomberg New Energy Finance, battery prices had fallen by 87% between 2010 and 2019. Prices are forecast to fall by 42.7% by 2030.

“The synergies between storage and PV are very consistent. The predictable daily on and off cycle of solar photovoltaics is well matched to the charging and discharging needs of the battery. With the increase in renewable energy sources, battery storage plays a vital role to successfully balance the load 24/7,” said Álvarez.

RatedPower customers can now design an AC coupled BESS. The BESS software module allows you to incorporate storage into new solar designs or into existing projects.

Traditionally, BESS sizing is based on the estimated nominal power of a PV installation, regardless of available land or BESS requirements, such as capacity optimization or electrical requirements. RatedPower has reversed the approach to optimize the area where the BESS is installed and consider supply chain duration or capacity optimization.

pvDesign automatically locates the battery containers and the power conversion stations at the defined location. It takes into account the operating hours of the batteries, calculates the length of the cables or carries out earthworks. It will also tailor the interconnection facility.

pvDesign generates the necessary documentation for the basic engineering of an AC coupled BESS, including layout, bill of materials and the design report. pvDesign also discloses the energy available to charge the batteries.
