在电力需求低的时期，特别是当需求降至基本负荷供应水平以下时，系统运营商在有效调度其发电机组方面可能会遇到困难。这些州被称为“最低发电条件(MGC)”，很麻烦，因为它们可能导致温室气体排放增加、电价下降或可再生能源整合的额外障碍。这项工作探索了在需求响应(DR)中使用电热水器(EWHs)的潜力，以减轻这些MGC的数量和严重程度。一种发现MGC的检测方法首次应用于加拿大安大略省的系统。在2018年可再生能源目标水平上，研究发现，大多数中期气候变化将发生在春季和秋季的凌晨。为了显著解决这一问题，采用DR的下一代EH需要10°C的死区才能实现所需的800多兆瓦。
During periods of low electricity demand, particularly when demand drops below baseload supply levels, a system operator can encounter difficulties in efficiently dispatching its generating units. Referred to as `minimum generation conditions (MGC),' these states are troublesome because they can lead to increased greenhouse gas emissions, depressed electricity prices, or additional barriers to renewables integration. This work explores the potential of using electric water heaters (EWHs), in a demand response (DR) role, to mitigate the number and severity of these MGCs. A detection method for finding MGCs is first applied to the system in Ontario, Canada. At 2018 renewables target levels, it was found that most MGCs would occur in the early morning of spring and fall. To significantly address this issue next generation EWHs employing DR would need a deadband of 10°C to enable the 800+MW required.
