With the increasing depletion of traditional fossil energy, it is urgent to develop multi-energy complementary technology to improve energy efficiency. In the context of the carbon-ne. In this section, joint planning and ex-post cost allocation modes for multiple PIESs with SES are proposed, whose detailed principle is shown in Fig. 1.•1). Based on the joint planning mode for multiple PIESs with SES, the JPM-OCTS is established in this section to minimize the total investment and operation costs of the grand cooperativ.
