On March 14, 2017, NEDO and the Ministry of Energy of Poland concluded a memorandum of understanding for the project to support the power system security in response to increasing share of renewables connected to the Polish power system. The project goal is to test on the assigned grid area functionalities of Special Protection Scheme (SPS) and hybrid Battery Energy Storage System (BESS) in order to increase power system security. The solution offered utilizes Japanese state-of-art network stabilization and battery storage technologies.
In order to carry out the project, Hitachi, Hitachi Chemical and SMBC each will sign an entrustment agreement with NEDO. Alongside this, Hitachi and Hitachi Chemical today signed an implementation document to realize the project in cooperation with PSE, EOP and EW.
As an EU member state, Poland plans to increase renewables energy ratio in its power system. In order to handle the additional burden on the electricity networks, essential work is required to upgrade and enhance the grid. This can be supported by utilization of advanced grid automatics such as SPS preventing the grid overloading and allowing for optimal management of renewables generation, especially wind generation.
Decision on project execution in the next three and a half year is based on the results of a feasibility study conducted from February 2015 to November 2016 by Hitachi, Hitachi Chemical, SMBC and other entrusted companies. More specifically, Hitachi working with PSE, EOP and EW will build SPS solution while Hitachi Chemical will be responsible for provision of hybrid BESS equipped with lithium-ion and lead-acid batteries. In addition, Hitachi, Hitachi Chemical and SMBC will explore business models for network protection systems and battery energy storage systems.
