和文要約
英文要約R&D Item (1): Enhanced wind power forecast and control technology
1-(1) Development of monitoring system for wind power and weather:
We are developing a new monitoring system, and collecting meteorological monitoring data in the eastern Japan.
1-(2) Development of ramp forecasting technology:
We conducted a benchmark test and summarized the problems of existing wind power forecasts. We categorized past weather conditions when a ramp occurred and analyzed its causes, scales, strengths, and frequencies.
In addition, we started improving controls for power generator outputs by using their short-term forecasts.
1-(3) Development of mitigation technologies for output fluctuations using storage energy
The concept of two kinds of use cases for wind power output control; “fluctuation mitigation” and “scheduled generation” were defined. Control algorithms for energy storage facility using forecasting information were developed for the use cases. The performance of the algorithms was examined by simulation calculation. We found that the use of forecasting information to control algorithms lead to the reduction of energy storage capacity required to achieve a certain level of control performance. In parallel with simulation study, construction of demonstration facilities for three kinds of energy storage technologies have progressed.

R&D Item (2): Network operation simulation with forecast technology
2-(1) R&D on the supply and demand simulation system:
In order to maximize the usage of renewable energy source (RES), a theoretical basis of optimum weekly operation scheduling of pumped hydro power plants and battery energy storage systems was studied. RES forecast error and the seasonal characteristics of photovoltaic generation were taken into account and the mathematical model of thermal unit restoration was improved.
The first version of prototype simulation system was designed and constructed based on the logic maps, which were prepared last fiscal year.
Models, constants, and parameters for simulations of eastern Japan power system were prepared to study RES -related issues.
2-(2) Field demonstration:
The following was carried out based on the test scenario to demonstrate a total cost minimization of the target electric power system.
*Development of an EMS prototype and decision of a system security guideline
*Installation of a weather monitoring equipment in local area, measurement start, development of the RES output forecasting system.
*Development of the power system model for simulating the frequency fluctuation caused by RES in the isolated island grid with the developed primary frequency control model of the diesel engine unit by the field test.
*Construction of RES and energy storage equipment, which imitate the output fluctuation by a large amount of RES installed in 2030.
