摘要:

新能源发电正经历从保护性并网模式迈向电力市场竞争模式的转型。然而,由于新能源发电的不确定性和间歇性,难以独立有效地参与电力市场竞争。为此,构建了一种基于新能源场站的风-光-储-氢混合电厂模型,旨在稳定供应电力、参与电力市场交易和满足氢能负荷需求。在电力市场环境下,以资产收益率(return on equity, ROE)最大化为原则,结合中长期与现货市场交易规则,建立双层优化配置模型;外层采用改进的麻雀搜索算法(improved sparrow search algorithm, ISSA)寻求最优配置策略,计算ROE作为适应度数值,内层采用混合整数线性规划求解具体运行策略。同时,引入电解槽产生氢气的二次多项式约束,并将其松弛转化为混合整数二阶锥规划(mixed-integer second-order cone programming, MISOCP)问题,形成混合电厂的优化配置方案。案例仿真结果显示,优化配置方案的ROE可达0.32,通过制氢效率特性的进一步优化运行,ROE可提升至0.35,实现了电能与氢能的有效融合,显著增强了新能源发电在电力市场中的竞争力。

Abstract:

Renewable energy generation is undergoing a transformation from a protected grid-connection model to a competitive electricity market model. However, due to its inherent uncertainty and intermittency, renewable sources struggle to independently and effectively participate in electricity market competition. To address this issue, a wind–solar–battery–hydrogen hybrid power plant model based on renewable stations is developed, aiming to ensure stable power supply, engage in electricity market transactions, and meet hydrogen load demand. Within the electricity market environment, a bi-level optimal configuration model is established with the objective of maximizing the return on equity (ROE), integrating both medium- and long-term as well as spot market trading rules. The outer layer uses the improved sparrow search algorithm (ISSA) to determine the optimal configuration strategy, using ROE as the fitness function; the inner layer applies mixed-integer linear programming (MILP) to solve specific operational strategies. In addition, a quadratic constraint is introduced to accurately model the hydrogen production curve of the electrolyzer, and this constraint is relaxed and transformed into a mixed-iInteger second-order cone programming (MISOCP) problem, thereby forming the hybrid power plant's optimal configuration scheme. Case simulation results show that the optimized configuration achieves an ROE of up to 0.32, which can be further improved to 0.35 through enhanced operation based on hydrogen production efficiency, thereby enabling effective integration of electricity and hydrogen energy and significantly enhancing the competitiveness of renewable generation in the electricity market.
