Construction of multi-variety combination trading model for electricity market

Abstract

At present, the actual situation of spot transactions in China's power market is relatively complicated, and it is necessary to expand diversified power products to meet different market participants. Therefore, we can introduce the Nordic power market block trading products as a reference to continuously improve our own construction. Combination transactions based on block transactions and their derivatives are aimed at enabling power market participants to choose transaction types that are more in line with their own characteristics and making transactions more flexible and diverse. Based on the current situation of China's high proportion of renewable energy, combined with the Nordic day ahead power trading model, this paper first analyzes the diversified trading needs, and designs flexible and diverse power market trading varieties. Then, we constructs a power spot market clearing model which considers the flexible combination of multiple trading varieties. The calculation example shows that the flexible transaction mechanism has greatly stimulated market vitality, achieving a high transaction rate and low abandonment rate on both the supply side and the demand side. While meeting the power demand of users, it also guarantees the interests of power generation entities with different economic characteristics.
