We combine our abundant findings and advanced IoT technologies that we acquired through establishment of electricity infrastructure and development of renewable energy technologies to optimally control the power supply-demand balance and to promote realization of energy service systems that are appropriate for the next generation.
To realize further advanced power transmission and distribution, we offer advanced solutions.
By introducing state-of-the-art IoT technologies, information of actual equipment can be captured to virtualize the power system on Toshiba's IoT architecture SPINEX™. That enables simulation of "power system operation" and "facility formation" to assist in making business decisions.
In order to realize an "improved facility utilization rate, operation rate and operational productivity" of power transmission/distribution facilities, we apply IoT technologies to, for example, minimize loans of personnel for inspection and fault handling, in an attempt of efficiency improvement.
A negawatt aggregator is a business operator who intermediates power business operators and consumers to aggregate multiple consumers and put together and trade the reduced power demand (negawatt). Through various demonstration projects by the Ministry of Economy, Trade and Industry, Toshiba has accumulated findings on demand fluctuations arising from various factors including consumer characteristics and the weather. By optimally combining consumers depending on the situation (portfolio), we supply negawatt with high accuracy.
Virtual power plant is our initiative to contribute to optimization of the supply-demand balance in the power network by effectively controlling and operating multiple energy generation and storage facilities such as solar power generation, storage batteries and hydrogen facilities scattered in the region to make them function like one power plant. Toshiba aims to build a virtual power plant by combining the power generation and transmission technologies it has accumulated and state-of-the-art IoT technologies to develop an energy management system that realizes effective control and operation of various facilities and equipment.
*1 VPP: Virtual Power Plant
By adopting the "IoT Standard Pack" we developed for IoT business operators, we have quickly built and introduced a storage battery cluster control system towards building a virtual power plant. The system is packed with a number of functions, such as visualization, remote monitoring, remote control and real-time charge/discharge control linked to the power market for storage batteries that exist at multiple facilities. In addition, utilizing our IoT architecture SPINEX™ enables adding new functions including predictive maintenance, O&M*2, and big data analysis.
*2 O&M: Operation and Maintenance
Based on the automatic feeding system for power companies we have provided for many years and the supply-demand control system enesuite™ for PPS, we will continue to provide solutions that meet the needs of each business operator.
Toshiba designs, develops and maintains smart meter communications systems to which the world's largest wireless multi-hop network is applied. The system shown below consists of communication units for smart meters, concentrators for relaying data, and head-end systems to gather and retain data. It enables automation of meter-reading work and detection of power outages.
Using this system, Toshiba contributes to establishing a social infrastructure which realizes both the implementation of various businesses and new services associated with energy liberalization and the economy of energy service businesses.
In addition to the development of various products, Toshiba works on integration business for the entire smart meter communication system including provision of support necessary for its operation. The business covers simulation for building a wireless network consisting of smart meters and concentrators, formulation of operation policies, and analysis and improvement of network quality. By repeating PDCA cycles as shown in the figure, we maintain the communication quality and realize stable operation of the system.
