TECHNICAL FIELD Embodiments of the present invention relate to a driving assistance system, a driving assistance device, a driving assistance method, and a program.

With the increase in power sources that prioritize renewable energy (hereafter referred to as “renewable energy”), thermal power sources are expected to play a role as a backup power source for fluctuating natural power sources, such as renewable energy, from power generation as a base or middle power source. ing. For this reason, thermal power sources have shifted to operations in which starting and stopping are frequently repeated. The load on the thermal power plant fluctuates according to changes in power demand and the amount of power generated by natural variable power sources such as renewable energy. In the electricity market, electricity prices are traded according to the supply and demand situation based on fuel costs.
Until now, the life consumption of parts such as high-temperature parts of thermal power plants has been managed by equivalent operating hours. Taking turbine blades as an example, the service life consumption time is calculated by accumulating the operating time weighted by the number of starts and stops and the number of trips, etc., in addition to the rated operating time.

In the future, it is expected that the introduction of variable natural power sources such as renewable energy will increase. Therefore, in the near future, it is impossible to predict whether or not thermal power plants will be able to adjust the supply and demand of electric power. Thermal power generators are required to be used in various ways, and it is expected that conventional life management based on equivalent operating hours will cause problems.
In addition, since the operation mode of the required backup power source differs according to the load fluctuation situation of the renewable energy power source, the power generation cost also differs. Therefore, optimizing the operation of thermal power generation facilities or correctly evaluating the value of each power source as a backup power source is essential for the formation of backup power source facilities, the stable supply of power, and the Feed-in Tariff (FIT) system. This is important from the viewpoint of cost reduction. To that end, it is important to evaluate the inertia force of thermal power generators and the ability to adjust frequency due to load fluctuations, as well as the non-fossil value of renewable energy power generation. In addition, in order to evaluate the value of thermal power equipment as a backup power source for renewable energy and promote facility formation, it is important to value each power source, including mobility and frequency adjustment value.
