“…Price-based programs are based on dynamic tariffs, where the prices of the tariff values change depending on the electric energy market circumstances and network conditions. Price-based programs based on time and power demand can be classified as the following [19]: time-of-use pricing, real-time pricing, and critical-peak pricing. In [20], a self-scheduling model for a HEMS is presented considering time-of-use pricing and real-time pricing, aiming to reduce the users' electric energy costs.…”

This paper addresses the issue of the abolition of annual net metering in Slovenia and compares the electric energy costs for the studied active user after the abolition. The article also provides an exploration of the role played by an aggregator, which serves as a central entity that enables individuals to participate in the electric energy market. An analysis of the case study of an active user was made, where an analysis was made of the measurements of household consumption and photovoltaic plant production for the year 2022. This article presents an economic analysis with and without net metering and an analysis of the aggregator involvement strategies. In addition, a battery energy storage system was also considered in the analysis. An important part of the article is the identification of the flexibility potential for shiftable loads, which enable an aggregator to acquire insight into the energy consumption profile and energy production profile of active users. The following indicators were used to compare the strategies: annual electric energy cost and the indicators including self-sufficiency, self-consumption, and grid dependency. The findings indicate that, even in the absence of annual net metering, the active user can lower their costs for electric energy with the help of an aggregator.

Power grids in the 21st century face unprecedented challenges, including the urgent need to combat pollution, mitigate climate change, manage dwindling fossil fuel reserves, integrate renewable energy sources, and meet greater energy demand due to higher living standards. These challenges create heightened uncertainty, driven by the intermittent nature of renewables and surges in energy consumption, necessitating adaptable demand response (DR) strategies. This study addresses this urgent situation based on a statistical analysis of recent scientific research papers. It evaluates the current trends and DR practices in buildings, recognizing their pivotal role in achieving energy supply–demand equilibrium. The study analysis provides insight into building types, sample sizes, DR modeling approaches, and management strategies. The paper reveals specific research gaps, particularly the need for more detailed investigations encompassing building types and leveraging larger datasets. It underscores the potential benefits of adopting a multifaceted approach by combining multiple DR management strategies to optimize demand-side management. The findings presented in this paper can provide information to and guide future studies, policymaking, and decision-making processes to assess the practical potential of demand response in buildings and ultimately contribute to more resilient and sustainable energy systems.

“…Both the power supply side (Takahashi et al, 2017) and the energy storage side (Meng et al, 2021) can be directly connected to dispatch. Unlike the abovementioned subjects, the load side's minimum regulation unit is the user, which the LA must integrate to provide grid regulation capacity.…”

China has promoted the development of the new energy power generation industry since 2013. However, the high proportion of unique energy access to the grid brings greater volatility and uncertainty. One effective way to solve these problems is incentivizing shiftable loads (SLs) to demand response (DR). The low enthusiasm of SLs lies in the lack of an effective incentive mechanism and strategy. Because the SLs’ initiatives participating in the DR are closely related to its structure of comfort and economic preference, we divided SLs into economical users (EUs), standard users (SUs), and comfortable users (CUs). Considering the balance of the benefits between the load aggregator (LA) and SLs and the impact of resource scarcity, we build the optimal incentive model based on the principal-agent theory under the case of symmetry and asymmetry information. Based on MATLAB simulation, we have the following suggestions for LA: 1) In terms of dispatch sequence, LA should dispatch SUs first and then EUs and CUs, 2) In the setting of retained earnings, EUs should be the most, followed by SUs, and the least is CUs, 3) In terms of incentive intensity, CUs need the most incentive, EUs need moderate, and SUs need the least, 4) LAs need to adjust the intensity of incentive contracts according to the scarcity of resources, 5) LAs should also improve their service to reduce users’ risk aversion to strengthen their effort level.
