This study developed an MPC-based bottom-up intra-hour proactive scheduling method for a set of thermal appliances to reduce the household peak load. The house-level peak load is formulated by the concurrent operations of multiple high-rate-power appliances. The controllable appliances can be separated into thermal and non-thermal appliances.
The household set selected had different consumption features, namely with varying characteristics in terms of the relation between the peak and base load and load fluctuations, which made it possible to take the heterogeneity of real-world load profiles into account (see Table 2). In addition, important issues determined the household selection, such as the power

Preface. This article from IEEE does a good job of explaining how and why it is incredibly expensive for cities to cope with with L2 chargers, EV, solar, and heat pumps by zeroing in on Palo Alto, where there are more EVs per capita than any other town in the U.S. Some key points: To achieve the desired reduction in greenhouse gases, renewable-energy
The effect of the transformer peak load reduction has also been analysed and found to be 2636%. Supposing that the actual peak load of a transformer without DLC is 0.7 p.u.

Peak shaving Power grid infrastructure is provisioned based upon expected peak power demand, so that during periods of unusually high demand, the grid is still able to handle the load. However, as a result, the grid often operates at a much lower load, resulting in expensive underutilised infrastructure.
Load smoothing results in a more predictable net load, which can help negate the need for expensive peak-plant generation. Peak shaving can improve network reliability by ensuring that peak power demand does not exceed a particular transmission and distribution capacity .
The results show that even though the number of peak events is significantly smaller in the second case the maximum size of the battery required for peak shaving does not vary. This is due to the fact that the maximum battery size is dictated by the longer duration events.
In particular, there has been a significant interest in the use of residential battery storage to offer services to the wider electricity grid by storing electricity during periods of low use (or high generation) and discharging during peak periods .
