Battery Storage Systems in Canberra, ACT plays a vital role in today’s energy blend. Industrial and commercial applications of battery storage allow electric grids to become more resilient and flexible. It enables grid operators to store energy generated by wind and solar at times when those resources are abundant and then discharge that energy at a later time when required.
For anybody working in the industry of energy storage, specifically developers, it is important to have a general idea about critical battery storage systems,and its related components and how these components work together.
There are various types of batteries used in the energy storage systems. Yet, for this guide, we will emphasize on lithium-based systems, the most rapidly growing and extensively deployed type representing most of the market.
In more detail, let us look at the vital components of a battery storage system.
The battery is a vital component in the battery storage system. It stores the energy ready to be dispatched when required. The battery comprises a fixed number of lithium cells wired within a series and parallel within a frame to create a module. The modules and ten combined and stacked to create a battery rack. Battery racks can be connected in parallel or series to reach the necessary voltage and current of the battery storage system. These racks are the building blocks for creating a huge, high power battery storage system.
You can witness the accumulation of the battery from cell to rack in the picture below.
Any lithium based energy storage system should have a Battery Management System (BMS). The BMS is considered the brain of the battery system, with its basic function being to protect and safeguard the battery from damage in different operational scenarios. To accomplish this, the BMS should make sure that the battery works within pre-determined ranges of various critical parameters, including state of health, state of charge, temperature, voltage, and current. More sophisticated battery management systems, such as those used by Daddy Sun Solar, have a multi-level framework that permits real-time tracking and protection of the battery and not just at the cell level but at the string, module, and system level. The BMS keeps on tracking the status of the battery and uses application based algorithms to analyze the data, control the environment of the battery, and balance it. This is important for the thermal management of the battery to assist in preventing thermal runway. A well designed BMS is an important battery storage system component and makes sure the durability and safety of the battery in any lithium battery storage system.
The battery system in the battery storage system stores and delivers electricity as Direct Current (DC) while most of the electrical systems and loads work on Alternating Current (AC). For this reason, Hybrid Inverter or PCS is required. These devices are more dynamic than standard inverters as they can convert power bi-directionally. This implies DC power from the battery can be transformed to AC power to charge the battery. This efficiently imparts the battery storage system its ability to both discharge and charge. The PCS gas different modes which can be set for different discharging and charging plans based on the particular application of the battery storage system. For the Hybrid inverter and PCS to be effective in the battery storage system, it should have access to the battery status, so it knows when to discharge and charge.
These are the vital components of the battery storage systems that make them valuable, effective and safe.
