随着分布式能源的广泛接入电网,将分布式电源整合管理的虚拟电厂技术得到了越来越广泛的关注。因为部分内部元素的不确定性,虚拟电厂调度策略要综合考虑收益和风险两方面,从而是一个多目标优化问题。该文引入考虑风险调整资本收益率指标建立了收益和风险的平衡关系,从而提出一种具有经济学含义的虚拟电厂优化调度模型;也引入经济资本概念作为虚拟电厂抵抗风险的准备金,并利用条件在险现金流指标确定经济资本的需求。通过实际示范项目作为算例,文中验证了调度模型的有效性;并且通过对比分析说明,组建虚拟电厂能够降低偏差惩罚,并提高分布式电源和负荷的购售电收益。

掺镁氧化铁电极光响应n-p型转换的研究

物理化学学报 1987年第1期3卷 1-3页

作者：蔡生民陆坦周牧易北京大学化学系厦门大学化学系

热形成氧化铁一般为n型光响应,掺Mg后有可能为p型。本文作者之一曾报导用涂敷方法制备的以Pt为基底的氧化铁膜随电极电势向负向移动,光响应由n型转为p型,但末作进一步研究。我们用工业纯铁制成的氧化铁电极则始终表现为n型光响应,原因... 详细信息

热形成氧化铁一般为n型光响应,掺Mg后有可能为p型。本文作者之一曾报导用涂敷方法制备的以Pt为基底的氧化铁膜随电极电势向负向移动,光响应由n型转为p型,但末作进一步研究。我们用工业纯铁制成的氧化铁电极则始终表现为n型光响应,原因可能是含Si0.005％所致。在本文中我们将工业纯铁片和分析纯MgO粉末直接接触,加热。在一定条件下可以得到具有n、p型双重光响应。溶液为硼酸、硼砂缓
