解释器：为什么新法规使网格不稳定

听这篇文章

中央电力监管委员会不到三周（CERC）新的法规脱钩偏差指控和频率，网格频率在12月20日疯狂而危险地挥舞着，这使电力行业震惊，并就监管变化对电网健康的影响发起了辩论。

A significant drop or rise in frequency could lead to a blackout.

Concerned about the security of the grid, the Commission hasreverted频率连接的偏差沉降机制（DSM）作为保护电网稳定性的临时度量。

Before the new regulation, maintaining a healthy grid frequency was monetarily productive for all stakeholders. The earlier regulation imposed penalties and incentives on power producers and consumers alike, which ensured that the grid frequency did not fluctuate dangerously.

However, the Commissionrevised偏差结算机制（DSM）框架现在已将偏差费用与在白天市场（DAM），实时市场和辅助服务市场中发现的时机价格联系起来。

在下面的图表中，可以看到全印度全印度频率清晰的跳跃和下降。

*每个CERC IEGC调节允许的频率范围为49.90-50.05 Hz

一家能源解决方案公司的高管说：“当需求超过一代时，频率往往会下降。基本上，这可以追溯到新的DSM法规。DSM的影响很高，可能会改变人们的安排能力。”

He added that frequency fluctuations could recur, and the Commission must work with Grid-India to ensure grid stability.

监管机构的新机制的理由

CERC曾说过，CERC曾说过，旧系统并不是发电是短暂还是盈余的可靠指标。它说，没有机会使用频率从价格套利中获利。

Speaking to Mercom, founder of a top renewable energy management company, said, “The earlier frequency-linked tariff had a barrier where both generators and buyers had to respond based on grid frequency.”

例如，以前，如果功率生产商计划在系统中但将2 GW注入系统，则该实体将根据频率对多余的能量进行惩罚。较早的价格信号源自频率连接的电价，

“利益相关者不会打扰频率，他们会考虑与频率无关的其他价格信号。另一个行业消息人士说：“由于法规的变化，这种偏差可能会变得更加复杂。”

Further, the Commission had based its decision on the introduction of ancillary services, which made the linkage of DSM price to frequency largely redundant. While ancillary services are deployed centrally by the system operator to restore and maintain system frequency closer to 50 Hz, the frequency-linked DSM price is a decentralized tool for controlling frequency.

Another reason cited by CERC was that the discipline in the grid had discouraged power distribution companies from waiting for the high-frequency period to draw power as the prices would dip very low during the period. But with grid frequency being maintained mainly within the recommended band, even the DISCOMs couldn’t take advantage of the price arbitrage.

但是，在没有过渡阶段的情况下取消链接频率会对印度电网产生影响。

“The grid is like a flywheel where the speed will increase if more energy is added. If people are not encouraged to consume more when the speed is high, the frequency will not return. There must be some linkage between deviation and frequency if we want to operate in a loose pool system, or we should move towards the European market design, where everyone must operate at a mandated frequency,” another source said.

A comparison of frequency trajectories

A comparison of the frequency profile is below, which juxtaposes three different periods. December 1, 2022, to December 20, 2022, vs. November 1, 2022, to November 20, 2022 (to assess the immediate effect of the implementation of the new regulation) and December 1, 2021, to December 20, 2021 (to see the impact of the season)

The chart clearly shows the impact of regulation in the December 1 to December 20 period compared with other more controlled periods during previous regulations.
