Japanese technology giant Hitachi has announced it will work with other six organizations and firms to deliver a smart grid demonstration project using hybrid (lithium-ion and lead-acid) battery energy storage system (BESS) in Poland.
The New Energy and Industrial Technology Development Organization and the Ministry of Energy of Poland have clinched a memorandum of understanding to support the Polish power system security.
The project is to test on the allocated grid area functionalities of a Special Protection Scheme (SPS) and hybrid BESS for the purpose of improvement of power system security.
The solution will employ Japanese state-of-art network protection systems and battery storage technologies.
Hitachi will work with state-owned grid operator Polskie Sieci Elektroenergetyczne, distribution network operator Energa Operator, and power supplier Energa Wytwarzanie to build Special Protection Scheme (SPS) solution, while Hitachi Chemical is to supply the hybrid BESS equipped with lithium-ion and lead-acid batteries.
SPS can prevent the grid overloading and optimise management of renewables generation, especially wind generation, according to Hitachi.
Poland plans to increase the renewable energy proportion in the domestic power system, which put additional burden on the electricity networks, upgraded and enhanced works are needed.
The project would be carried out in the next three and a half year.
Hitachi will associate with Japan’s Sumitomo Mitsui Banking Corporation to investigate business models for the network protection systems and BESS.
