21世纪电力系统的灵活性
简介
电力系统最基本的规则是发输用电必须同时完成。多年来，电网运营商一直在确定系统的负荷，并通过增加可用的发电机来满足需求、调整供电。
然而，现在供应侧出现了快速爬坡和高度灵活的联合循环燃气轮机发电等新技术，需求侧也出现了智能热水器和储能等新...

Navigare necesse est: Rerouting network companies toward decarbonisation
Changing the course of a sailboat requires coordinated action. The skipper announces the manoeuvre to the crew, turns the rudder and works with the crew to readjust the sails. To achieve the maximum cruising speed with the prevailing winds and currents, all sails need to be swiftly positioned at just the right angle.
The need for fluid coordination also applie...

减少弃风：提高电力系统调度比改造燃煤电厂更高效
中国的风能和太阳能装机容量世界第一，且有望成为“世界可再生能源的超级大国”。然而，中国也遇到了弃风限电问题。虽然近年来可再生能源弃电量有显著下降，但在很多省份仍然存在问题，且将随着风能和太阳能发电装机量的增长而持续成为挑战。幸运的是，政府部门...

Improving Power System Dispatch Reduces Wind Curtailment More Effectively than Retrofitting Coal Plants
China has the most installed wind and solar capacity in the world and has potential to become “the world’s renewable energy superpower.” However, China’s power sector has also struggled with extensive curtailment of wind and solar generation. Although renewables curtailment has dropped significantly in recent years, it is still an issue in large parts of ...

A Hearty Bowl of Texas Soup: How ERCOT Keeps the Lights On
ERCOT (or the Electricity Reliability Council of Texas, the independent system operator of that state’s stand-alone wholesale market) has confounded the doomsayers once again. Despite dire predictions that ERCOT lacked sufficient generation capacity, it came through the peak summer season of 2019 without any firm load curtailments, despite a hotter-than-normal ...

UK capacity market déjà vu: A solution that’s still in search of a problem
In November 2018, the EU General Court ruled in favour of a legal challenge mounted by Tempus Energy to the Directorate General for Competition’s (DG COMP) approval of the capacity market in Great Britain. In its challenge, Tempus successfully argued that, due to serious flaws in the design of the capacity market, DG COMP should have had doubts over its compati...

Stuck in the past: Energy performance certificates hold back heat decarbonisation
In 2014, we bought an old Victorian house in Oxford, UK, well aware it needed major renovation work. Our energy performance certificate (EPC), which shows the energy performance of a building, was a poor grade “E” on a scale of A to G, with A being the highest performing category. We have since carried out a major refurbishment programme, installing underfloo...

Emissionspreise sind nicht alles
Preise für Emissionen sind nicht alles, vielmehr ist die sinnvolle Verwendung der Einnahmen entscheidend. Schlüssig belegt ist, dass Energieeffizienzprogramme gut abschneiden. Auch das Ordnungsrecht – zum Beispiel Mindeststandards – helfe bei der Einhaltung der Klimaziele.
Das Klimapaket der Bundesregierung ist derzeit in aller Munde. Wie auch die darin ...
