The development of energy storage technology (EST) has become an important guarantee for solving the volatility of renewable energy (RE) generation and promoting the transformation of the power syste.
What are the challenges of large-scale energy storage application in power systems?
The challenges of large-scale energy storage application in power systems are presented from the aspect of technical and economic considerations. Meanwhile the development prospect of global energy storage market is forecasted, and application prospect of energy storage is analyzed.
The development and expansion of energy storage technology not only depend on the improvement in storage characteristics, operational control and management strategy, but also requires the cost reduction and the supports from long-term, positive stable market and policy to guide and support the healthy development of energy storage industry.
During entry and exit of distributed generations, the power is out of balance in a short time, the energy storage facility can be applied to realize fast charging/discharging control, and active power is able to be controlled smoothly and instantaneously to guarantee the voltage stability of significant load.
Due to rapid development of energy storage technology, the research and demonstration of energy storage are expanding from small-scale towards large-scale. United States, Japan, the European Union have proposed a series of policies for applications of energy storage technology to promote and support industrial development [12 – 16].
Most technologies are not passed down in a single lineage. The development of energy storage technology (EST) has become an important guarantee for solving the volatility of renewable energy (RE) generation and promoting the transformation of the power system.
The application of energy storage technology in power system can postpone the upgrade of transmission and distribution systems, relieve the transmission line congestion, and solve the issues of power system security, stability and reliability.
