確率最適化を用いた需給調整市場の約定問題

In the electricity system reform currently being promoted in Japan, the transmission and distribution division in general electric power companies will be legally unbounded as a power transmission and distribution business operator (TSO) in 2020 to ensure the neutrality of the transmission and distribution business. TSOs procure the reserves through a public offering, but from 2021 they are going to procure the reserves through the reserve market. For the time being, TSOs will make a contract in a merit order of the ability of the reserves, called ΔkW, at the time of procurement. Then, TSOs will activate the reserves out of the procured ΔkW in a merit order of electric energy, called kWh, at the time of operation. However, to minimize the sum of procurement cost and operation cost, it is necessary to study the clearing problem considering ΔkW and kWh values. In this paper, we propose a clearing problem that considers ΔkW and kWh values simultaneously in the reserve market, then, using stochastic optimization we formulate the clearing problem as a 0-1 mixed integer programming problem.
