Abstract
The community integrated energy system can provide users with reliable, high-quality and economical energy supply by coordinating various energy equipment. However, the uncertainty of source and load and the off-design performance of equipment may easily lead to large energy supply/consumption deviation. To solve this problem, this paper proposes a collaborative optimal scheduling method considering source-load uncertainty and off-design performance. First, a collaborative optimization integrated model of community integrated energy system considering the off-design performance is established, and the uncertainty of source and load is represented by nonlinear interval number. Then, the nonlinear interval number is determinedly converted by using the interval possibility degree, and off-design performance curve is processed by adaptive piecewise linearization. Finally, an actual community integrated energy system is taken as an example for simulation verification. The simulation results show that the proposed method can effectively reduce the adverse effects of source-load uncertainty and off-design performance.
