论文摘要
电力网格从化石燃料到可再生能源的过渡引起了推动其运营的市场清除算法的基本挑战。实际上,负载的随机性增加以及可再生能源的波动性导致预测错误大大增加,从而影响了现有的确定性优化模型的可靠性和效率。 RAMC项目旨在调查如何从确定性的环境转变为一个风险感知的框架,在该框架中,明确量化了不确定性并将其纳入市场清除优化。风险了解的市场清除主要是从计算的角度出发的挑战。本文回顾了RAMC如何处理风险感知的市场清算,并在不确定性量化,优化和机器学习方面介绍了一些创新。提出了真实网络的实验结果。
The transition of the electrical power grid from fossil fuels to renewable sources of energy raises fundamental challenges to the market-clearing algorithms that drive its operations. Indeed, the increased stochasticity in load and the volatility of renewable energy sources have led to significant increases in prediction errors, affecting the reliability and efficiency of existing deterministic optimization models. The RAMC project was initiated to investigate how to move from this deterministic setting into a risk-aware framework where uncertainty is quantified explicitly and incorporated in the market-clearing optimizations. Risk-aware market-clearing raises challenges on its own, primarily from a computational standpoint. This paper reviews how RAMC approaches risk-aware market clearing and presents some of its innovations in uncertainty quantification, optimization, and machine learning. Experimental results on real networks are presented.
