有人建议，价格信号可以带来更大的需求方灵活性，从而支持风能等可变能源的整合。在保持这些信号对消费者的简单性，同时使反应适合于未来日益复杂的供需平衡动态之间存在冲突。本研究回顾了在分时电价（ToU）试验中观察到的一些需求响应，并评估了其在风力水平较高的情况下的有效性。作者模拟了高风力场景的批发实时价格作为基准电价。简单的关税结构与实时价格进行比较，以确定它们能够在“正确的方向”上“推动”需求的程度。他们提出的结果表明，即使在高风速的情况下，简单的ToU关税也可能对整体系统成本产生有益的影响。在ToU试验中观察到的负荷转移和减少行为可以将能源成本降低4%至6%，而无需复杂的价格信号。
Price signals have been suggested to bring about greater demand side flexibility and thus support the integration of variable sources of energy, such as wind. A conflict exists between keeping these signals simple for consumers, while making responses appropriate for increasingly complex supply–demand balancing dynamics in future. This study reviews some of the demand responses observed in time-of-use (ToU) tariff trials and assesses their effectiveness in scenarios with higher levels of wind. The authors simulate wholesale real-time prices for high-wind scenarios as a benchmark tariff. Simple tariff structures are compared against real-time prices for the extent to which they can ‘nudge’ demand in the ‘right direction’. They present results which suggest that even in high-wind scenarios, simple ToU tariffs could have a beneficial effect on overall system costs. The load shifting and reduction behaviour observed under ToU trials could lower energy costs by between 4 and 6% without the need for complex price signals.
