Summary: This paper proposes a multi-criteria evaluation method for microgrids to maximize their comprehensive value, and a case study in Japan shows the superiority of multi-objective optimization. Balancing economic benefits, peak shaving, and carbon reduction, high requirements for carbon reduction can promote renewable energy development, while peak shaving ability should be ensured by stable power generators.

Summary: Delaying battery replacement has significant economic benefits, as letting the battery degrade to 50% of initial capacity is comparable to a 30% reduction in battery capital cost during the project lifetime. The ability of a building to benefit from solar-plus-storage depends on the degradation limit and tariff structure, but not strongly on load pattern and size. Time-of-use tariffs are expected to promote rapid cost-effective adoption of PV systems with batteries in commercial buildings in the near future.

Summary: This paper proposes a new concept of a microgrid aggregator to coordinate the operation of microgrids in a multi-microgrid system, in order to avoid tie-line power congestion. A bi-level optimization model is used to control the trading power between microgrids, and demand response programs are activated through dynamic real-time pricing for rescheduling to achieve maximum profit.

Summary: The exponential growth of electric vehicles has led to an increased electricity burden, which can be addressed through demand-side management. This paper proposes a methodology for estimating Time-of-Use tariffs using big data technology to enable optimal demand-side management using electric vehicles. Simulation results show that the proposed method effectively reduces peak consumption by 6%-7%.

Summary: Compared to flat rate pricing, time-of-use electricity rates incentivize households to reduce electricity consumption during expensive peak hours. This study investigates the factors that impact voluntary enrollment in time-of-use plans and identifies potential strategies for utilities to increase enrollment. A survey experiment was conducted with residents in the United States, randomizing variables such as peak to off-peak price ratios, peak hours, and the number of plans offered. Findings suggest that the ability to compare plans plays a significant role in enrollment decisions, with respondents being more likely to enroll when multiple plans are available. Additionally, respondents show a preference for plans with larger price spreads and shorter on-peak periods.

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: The contribution of thermal power will change to peak-shaving power supply in the future. Combined heat and power plants in northern China are mainly used for central heating. This study establishes an evaluation method for cogeneration peak shaving based on the marginal cost of power generation during peak and valley periods. Four peak shaving methods are analyzed for their characteristics and applicability. The evaluation method provides a foundation for configuring cogeneration power peak shaving systems.

Summary: This study evaluates the integration of a vapor compression cycle with a phase change material (PCM) storage tank through experimental analysis in five cities with different weather conditions. The results show that adding the PCM tank decreases the total daily COP of the AC system compared to the conventional AC unit, but the AC plus PCM system performs better during on-peak hours. Adding the PCM storage tank increases total electric energy consumption over 24 hours, but it also helps in shaving the electric peak load.
