Summary: Demand response refers to changes in power consumption by electricity users in response to certain conditions on the electricity market. However, only a small percentage of respondents actually qualify through all three stages of the proposed framework for making informed decisions on how to act. The findings suggest a need for research and policy to shift focus towards alternative or improved strategies for communication and engagement.

Summary: This paper uses the two-threshold nonlinear autoregressive distributed lag (NARDL) model to analyze the asymmetric effects of electricity prices on industrial electricity demand in India from 1981 to 2016. The results indicate that customers react more strongly to a large price cut than a large price increase, while a small price change has no impact on electricity consumption. A large price decrease raises the quantity demanded by a higher percentage, making it more challenging to achieve net-zero emissions as electricity generation relies heavily on fossil fuels. Due to inelastic demand for price increases, a large price hike minimally reduces electricity consumption.

Summary: African power sectors face financial instability, low grid connection rates, and high consumer prices. Electricity tariff reform is a tool to address these issues. Payment reform can encourage electricity conservation and limit arrears. Block tariff structures are problematic and do not accurately target consumers. There is limited research on volume differentiated tariffs or subsidies. Electricity demand is price inelastic, and tariff increases should consider protecting low-income consumers.

Summary: This study analyzes a large-scale Time of Use (TOU) pricing experiment in South Korea. The results show that households effectively reduce peak demand in response to higher prices. However, the price responsiveness of the treatment groups decreased in the post-experimental period, resulting in increased intermediate consumption. This suggests a need to reexamine the price schedule under TOU pricing for social welfare.

Summary: This paper estimates the price and income elasticity coefficients of domestic electricity demand in South Africa from 1980 to 2018. It finds that electricity consumption was unresponsive to price changes when real electricity prices were falling, but the price elasticity coefficient increased markedly when real prices started increasing. Policymakers should take note that aggregate price sensitivity is notably higher when real prices are increasing, potentially leading consumers to switch to alternative energy sources.

Summary: An improved optimization model for demand response in a remote off-grid microgrid in Dongfushan Island, China is proposed in this study. The model considers different electricity prices under different seasonal meteorological conditions, aiming to develop energy dispatch and economic benefits. By using an improved Pareto optimum and distributed learning algorithm, the model maximizes satisfaction, reduces electricity bills for consumers, and increases profits for retailers. Simulation results show that the proposed method can lower electricity bills for consumers and help retailers save on generation costs and increase renewable energy utilization.

Summary: This study estimates household electricity demand using data from the 2015 Residential Energy Consumption Survey. The results show that price elasticity is influenced by household income and the number of appliances. As income increases, households rely less on electricity for heating but have more electronic appliances. These findings have important policy implications for electricity demand and low-income households.

Summary: Rooftop distributed photovoltaics have the potential to achieve deep decarbonisation in the residential sector. However, the intermittent nature and lack of dispatchability of photovoltaic output poses urgent challenges for large-scale deployment. This study develops a techno-economic evaluation framework that considers various factors, such as electricity price mechanisms, battery energy storage, demand response, and residential electricity demand, to enhance self-consumption and economic benefits. The results demonstrate that electricity price mechanisms greatly impact the economic benefits, with time-of-use pricing being more favorable. Installing battery energy storage and participating in demand response can improve self-consumption and self-sufficiency rates, resulting in more savings on electricity bills. Lower feed-in tariffs enhance the relative economic benefits of battery energy storage and demand response. Moreover, the ratio of annual residential electricity demand to photovoltaic power generation affects the self-consumption rate. Efficient time-of-use pricing mechanisms and lower feed-in tariffs can encourage residential consumers to adopt rooftop distributed photovoltaics, battery energy storage, and demand response.

Summary: The study proposes two methods to approximate hourly marginal emission factors and simulates standardized daily load shifts for 20 European countries. Results show that some countries experienced an increase in carbon emissions by 2.1%, and MEF-based load shifts reduced resulting carbon emissions by 35% but with 56% lower cost savings compared to price-based load shifts. Additionally, the analysis of different carbon price levels indicated that PBDR can be an effective tool for both economical and environmental improvement with adequate carbon prices.

Summary: Modeling of distribution networks has been renewed due to the dynamic phenomena arising from the increasing penetration of distributed generation. Different models and identification methods have been proposed to represent the response of distributed generation. However, no single model can capture all possible dynamic behaviors of distribution networks. To address this issue, this paper presents a method that automatically selects model structures based on informative events, allowing for parameter identification and model validation.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.
