Research on the Optimized Operation of Hybrid Wind and Battery Energy Storage System Based on Peak-Valley Electricity Price
Considering the peak–valley electricity price, an optimization model of the economic benefits of a combined wind–storage system was developed. A charging/discharging strategy of the battery storage system was proposed to maximize the economic benefits of the combined wind–storage system based on the forecast wind power.

A peak-valley tariff is considered in this case according to Table 1. As shown in Figure 9, EV loading on the system is the same as in Case 3 but the FC adjusts its output to take benefit of the
Peak-off-peak load shifting: Are public willing to accept the peak and off-peak time of use electricity price
The main purpose for the peak and off-peak pricing program is to induce energy consumers to eliminate their demand in the peak period by shifting peak load to off-peak period. The peak and off-peak pricing allows a 30–50% price hike during peak hours and a 30–50% discount during off-peak period ( State Council, 1985 ).

As a result, the economic benefits of ES primarily come from the "peak-valley price difference" of peak regulation. Therefore, how to construct the "peak-valley price difference" boundary value model in electricity
Peak Demand: What Is It And Why Does It Matter? | EnergySage
The impact of solar on peak demand. Peak demand typically occurs during the heat of the day in summer, which are the exact same times when solar panels produce the most electricity. As a result, solar can help offset your pull from the grid during those peak hours, lowering the overall need for power and reducing your individual peak
Research on Economy of Electrochemical Energy Storage

Economic viability of battery energy storage and grid strategy: A
The peak-valley price variance affects energy storage income per cycle, and the division way of peak-valley period determines the efficiency of the energy
Research on the Peak-Valley Time-of-Use Electricity Price
Research on the Peak-Valley Time-of-Use Electricity Price Mechanism for Power System Flexibility Enhancement Abstract: Renewable energy has the characteristics of randomness and intermittency. When the proportion of renewable energy on the system power supply side gradually increases, the fluctuation and uncertainty of the system power supply side
Optimization analysis of energy storage application based on electricity price
From the perspective of economic value, ESSs can help realize peak-valley arbitrage [12] and lessen the system''s energy loss by storing electric energy during the valley period and releasing it
Scheduling Strategy of Energy Storage Peak-Shaving and Valley-Filling Considering the Improvement Target of Peak-Valley
In order to make the energy storage system achieve the expected peak-shaving and valley-filling effect, an energy-storage peak-shaving scheduling strategy considering the improvement goal of peak-valley difference is proposed. First, according to the load curve in the dispatch day, the baseline of peak-shaving and valley-filling during peak-shaving
Residential electricity pricing in China: The context of price-based
Price based demand response (PBDR) is one of the two major DR programs. In this paper, we first introduce the pricing theories in economics, the pricing of electricity and the development of electricity pricing in China. Then, we present a detailed discussion on the PBDR strategies in the DSM of smart grid.
