  Industrial demand response (IDR) plays an important role in promoting the
utilization of renewable energy (RE) in power systems. However, it will lead to
power adjustments on the supply side, which is also a non-negligible factor in
affecting RE utilization. To comprehensively analyze this impact while
enhancing RE utilization, this paper proposes a power demand-supply cooperative
response (PDSCR) strategy based on both day-ahead and intraday time scales. The
day-ahead PDSCR determines a long-term scheme for responding to the predictable
trends in RE supply. However, this long-term scheme may not be suitable when
uncertain RE fluctuations occur on an intraday basis. Regarding intraday PDSCR,
we formulate a profit-driven cooperation approach to address the issue of RE
fluctuations. In this context, unreasonable profit distributions on the
demand-supply side would lead to the conflict of interests and diminish the
effectiveness of cooperative responses. To mitigate this issue, we derive
multi-individual profit distribution marginal solutions (MIPDMSs) based on
satisfactory profit distributions, which can also maximize cooperative profits.
Case studies are conducted on an modified IEEE 24-bus system and an actual
power system in China. The results verify the effectiveness of the proposed
strategy for enhancing RE utilization, via optimizing the coordination of IDR
flexibility with generation resources.
