In this paper, a two-stage robust optimization approach is employed to address the variability in renewable energy output by accounting for uncertainties associated with wind and solar energy. The model aims achieve balanced system that both low-carbon economically efficient while also being resilient uncertainties. Initially, regional integrated developed, integrating electricity, gas, heat. of photovoltaic power outputs represented using modifiable uncertainty set. A optimal scheduling formulated two stages, objective minimizing costs under worst-case scenarios. This solved iteratively through column constraint generation approach. Additionally, incorporates horizontal time shifts vertical complementary substitutions carbon trading demand-side loads avoid excessive conservatism manage emissions (RIES). Results show significantly enhances system’s resilience risks minimizes economic losses. inclusion mechanisms demand response prevents from becoming overly robust, which could impede growth, reducing emissions. proposed method effectively achieves economical, system.

The integration of a distributed generator (DG) into the distribution network alters topology structure and power flow distribution, subsequently causing changes in loss. Moreover, existing optimization methods face high computational complexity, low efficiency, susceptibility to local optima. This article proposes scenario generation method using generative adversarial (GAN) handle uncertainty associated with DGs constructs two-layer model for network. upper layer determines installation location capacity energy storage systems lowest economic cost. lower establishes an model, including wind, solar, storage, active loss voltage deviation as objective functions. Both layers are solved Improved Whale Optimization algorithm (IWOA). Then, IEEE-33 node system was taken simulation example verify effectiveness superiority proposed algorithm.
