实时市场运营中的内部水电和风电组合优化
Internal hydro- and wind portfolio optimisation in real-time market operations
摘要：
在本文中，有关方面处理的一天内不平衡的水电和风电。建立了不平衡成本的定义，并用于描述从工厂特定的时间表转移到相同价格区域的风电和水电机组的共同负荷要求的潜在好处。Nordpool日内按出价支付市场一直是评估失衡的基础，并描述了该市场的一些主要特征。我们考虑如何在同一河流系统内的内部处理的补充不平衡，高流入的不确定性和限制水库可以减少波动，短期的边际成本和风险相比，在日内市场交易。我们还表明，对于同时拥有风电和水电资产的发电商，可以通过内部平衡结合按出价支付的日内市场中的销售和购买来降低不平衡成本
英文摘要：
In this paper aspects related to handling of intraday imbalances for hydro and wind power are addressed. The definition of imbalance cost is established and used to describe the potential benefits of shifting from plant-specific schedules to a common load requirement for wind and hydropower units in the same price area. The Nordpool intraday pay-as-bid market has been the basis for evaluation of imbalances, and some main characteristics for this market has been described. We consider how internal handling of complementary imbalances within the same river system with high inflow uncertainty and constrained reservoirs can reduce volatility in short-term marginal cost and risk compared to trading in the intraday market. We have also shown the the imbalance cost for a power producer with both wind and hydropower assets can be reduced by internal balancing in combination with sales and purchase in a pay-as-bid intraday market
