The Polish electricity network operator introduced a smart grid system – the Special Protection Scheme (SPS)

PSE (Polskie Sieci Elektroenergetyczne) the Polish network operator introduced a innovative solution the SPS system, which automatically eliminates the overload on the transmission and distribution network 110 kV.

The system is the first result of a project of Polish and Japanese companies: PSE, ENERGA-OPERATOR (EOP), Energa OZE (EOZ), Hitachi, Hitachi Chemical and Sumitomo Mitsui Banking Corporation (SMBC). The cooperation was possible thanks to an agreement signed by the Polish Ministry of Energy and the Japanese New Energy and Industrial Technology Development Organization (NEDO) in 2017.

The system covers north of Poland and increases the security of the electricity network by eliminating the overload occurring from the power generation of the northern wind parks and making recommendations to distributers on how to eliminate the overloads.

The implementation of the SPS is the beginning of a cooperation of Polish and Japanese companies. The construction of a hybrid electricity storage unit (BESS) is underway, which will be connected to the Bystra wind park owned by ENERGA OZE. Both systems will help regulate the fluctuations in power generation, power reserves and frequency.

PSE is one of the first companies in Europe to implement smart grids. SPS can significantly improve the functioning of the national electricity network facing wind power generation and therefore help increasing the share of renewable energy.

The system will be monitored for one year until October 2020. During this time the effectiveness of the system will be measured also combined with the electricity storage unit.
