Until now, the load dispatching system, which serves to balance the amount of electricity used (demand) and generated (supply), had been developed by the transmission and distribution companies in each area.
With increasing complexity and variances in the operation of the electrical grid and the promotion of merit orders in nationwide areas, there is a need to develop a platform that is scalable, flexible, and transparent for future regulation changes and can be commonly used by all operators, in order to achieve improved resilience and social cost reduction. Against this backdrop, the nine general transmission and distribution companies (excluding the Okinawa area) have decided to standardize their load dispatching systems, and Hitachi has been contracted to build the system.
Hitachi has a track record of developing mission-critical systems for electric power companies in Japan, including the current load dispatching system. Furthermore, globally, we have a wealth of experience in introducing core systems and solutions related to balancing the energy market by Hitachi Energy. In addition, Hitachi Energy's packages are also used in Japan's energy market balancing system, which requires close collaboration in this system.
Based on Hitachi Group's unique achievements, the System will perform a wide-area Load Frequency Control (LFC5) function that will be introduced for the first time in Japan, as well as optimization calculations for nationwide generator start-stop planning and supply and demand control (SCUC6/SCED7 functions). In this way, by combining Hitachi's extensive experience in core system development with Hitachi Energy's global implementation experience and packages, we will build a system that leverages IT, OT, and products. The synergy within the Hitachi Group, combining digital and software technologies, will provide a more stable electricity supply and the use of renewable energy and contribute to the realization of carbon neutrality.
