Study on Medium- and Long-term Market Trading Curve Adapted to Spot Market

With the deepening of the electricity reform and the pilot construction of the electricity spot market, how to connect the medium- and long-term market with the spot market has become a very important issue. The curve decomposition of medium- and long-term contracts is one of the key elements for the connection between medium- and long-term market and spot market. Most of the traditional curve decomposition methods follow the order of year-month-week-day. Although it can realize the time scale consistency with the spot market at the level of electricity, it fails to take into account the value of electricity in different time periods, and the flexibility of market players in adjusting supply and demand is not enough. As a new trading mode, time-segmented energy block trading can reflect the spatial and temporal value of electricity, but in the current practice, it also reflects the problems that the time slot division is too fixed and the relationship with curve decomposition is not clarified. Therefore, the curve decomposition under the time-segmented energy block trading model and the trading strategy are proposed.
