IoT solutions for power transmission and distribution operators through virtualization of power system

Asset management to support business judgment through analysis of management resource data

Asset management

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.

Improving the efficiency of maintenance and facility operation

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.

Negawatt aggregator services to intermediate consumers and power business operators

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 (VPP*1) to simulate control and operation of various facilities and equipment

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.

Storage battery cluster control system to realize a virtual power plant utilizing IoT technologies

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.

Energy management system to perform power supply-demand adjustment in a grid

μEMS that supports local production and local consumption of renewable energy

The key product at Toshiba for Smart Grids is the μEMS. The μEMS offers in-grid supply-demand adjustment functions in cooperation with power business operators. It supplies power from solar power generators or storage batteries depending on the demand while monitoring and predicting the power consumption of consumers in real time, and controls power supplies for equipment used in households and office buildings. The μEMS maintains a balance between supply and demand of power, and realizes effective utilization of renewable energy, reduced energy loss, and reduced energy consumption.

μEMS functions are:

  1. μSCH: Overall energy supply and demand planning
    Performs operation planning based on PV output forecasts and demand forecasts.

  2. μELD: Financial burden distribution control
    Performs control of generators and storage batteries in long periods (in the order of minutes).

  3. μLFC: Real-time load frequency control
    Performs control of generators and storage batteries in short period (in the order of seconds).

Off-grid solutions to solve energy issues for remote islands

They are solutions to conclude supply and demand of power within isolated places such as remote islands by suppressing fluctuations in renewable energy using μEMS that supports local production and local consumption of renewable energy and storage batteries, stabilizing the system and reducing the fuel cost of diesel generators. It realizes effective utilization of surplus power and a highly-efficient stable power supply.
In the "Miyako Island Micro Grid Project for Okinawa Electric Power Co., Inc." conducted in 2010, we combined thermal power generation (diesel and gas) and renewable energy (solar power and wind power) to generate power.
We can also provide solutions to micro grids connected to a power system.

Storage battery system

Storage battery system that contributes to expanded use of renewable energy

This system maintains a balance between supply and demand, and appropriately supplies power by supplementing power from batteries when the power demand increases.
The output of wind power generation and solar power generation fluctuates depending on the weather conditions. This system contributes to solving various problems, including improving the supply-demand balance associated with expanded use of renewable energy and implementing measures against frequency fluctuations.
