要約(英語): In order to realize the carbon neutral society, it is essential to replace the legacy thermal power plants using fossil fuels by alternative sources. The authors investigate a potential of a microgrid for electricity, heat and hydrogen supply, in generation and balancing capacities perspective. Contributions by a microgrid are measured in terms of the amount of electricity purchased from the grid, the variation of im- and exporting power, and the available demand-supply balancing capacity. This paper estimates the additional cost for securing demand-supply balancing capacity in a microgrid, based on an optimal capacity design considering annual operation. The estimation results shows that the additional cost is enough comparable to the current balancing cost. In other words, the balancing power currently secured mainly by thermal plants could be replaced by microgrids at a lower cost. Especially, the introduction of hydrogen supply facilities is effective for both generation capacity measured in the amount of electricity purchased, and balancing capacity.
