The promotion of renewable energy, such as photovoltaic generation (PV), may worsen demand and supply balancing in the power system due to the large generation fluctuations of weather conditions in renewable energy. The electrolyzer for hydrogen supplying called the power to gas can regulate demand and supply balancing as alternative resources. The authors had developed a novel method to optimize the operation of microgrid consisted PV, battery, electrolyzer, and auxiliary equipment regarding hydrogen supplement participating in the reserve market economically. Previous research by authors evaluated the cost evaluation of hydrogen supply by electrolyzer in microgrid under optimization in ideal conditions based on time-series data of actual transaction prices in supplemental reserve market in Transmission and Distribution Grid Council (TDGC), and the spot market in Japan Electric Power Exchange (JEPX) had been performed. This research evaluates the cost of hydrogen supply based on the 2021 fiscal yearly actual prices and frameworks of domestic (Japan) and abroad (Germany) markets. Moreover, the evaluation reveals the effect of the cost of hydrogen supply on the difference in markets.

When Install a microgrid system (MGS) for consumers, it is important to install equipment according to the load of the consumer. Therefore, we will optimize the capacity of each MGS facility from the viewpoint of life cycle cost (LCC), which is the sum of initial cost and running cost. As an optimization method suitable for this, we propose a method that optimize the capacity of each MGS facility by particle swarm optimization (PSO) based on a one-year MGS operation plan using patterned data and mixed integer linear programming (MILP). The problem with this method is that it takes a long time to calculate the yearly operation. By expressing the customer data for one year with four types of pattern data while maintaining the characteristics of the data for each season, the amount of calculation required for the operation plan can be reduced and the optimum installed capacity can be obtained within the practical time.
When the proposed method was executed under multiple conditions and a case study was conducted to find the installed capacity, problems and room for improvement due to the randomness of PSO were clarified, but the combination of installed capacity with a small LCC was found. -

The promotion of renewable energy such as photovoltaic generation (PV) may worsen demand and supply balancing in the power system due to the large generation fluctuations by weather conditions in renewable energy. The electrolyzer for hydrogen supplying called the power to gas can regulate demand and supply balancing as alternative resources. The authors had developed the novel method to optimize the operation of microgrid consisted PV, battery, electrolyzer, and auxiliary equipment regarding hydrogen supplement participating in reserve market economically. Moreover, previous research evaluated its regulation ability and economic valuation through numerical case studies with expected transaction prices of the reserve market. This paper conducts the cost evaluation of hydrogen supply by electrolyzer in microgrid under optimization in ideal conditions based on time-series data of actual transaction prices in supplemental reserve market in Transmission and Distribution Grid Council (TDGC) in addition to the spot market in Japan Electric Power Exchange (JEPX). Moreover, this paper discusses the expected benefits of hydrogen supply with electrolyzer given by the reform from the current transaction system in electricity and reserve markets.
