Research on the Peak-Valley Time-of-Use Electricity Price
Renewable energy has the characteristics of randomness and intermittency. When the proportion of renewable energy on the system power supply side gradually incr.
By setting different peak-valley electricity price spread, the electricity consumption changes in the process of gradually increasing peak-valley electricity price differentials are studied. Renewable energy has the characteristics of randomness and intermittency.
To begin with, this study has demonstrated that peak-valley pricing policy designed to reflect the marginal costs principle and ensure trading activities in LEMs benefit consumers and prosumers at the expense of the power grid.
Because the price clearing process is treated as an exogenous variable in this market, a linear programming (LP) approach is adopted to solve for the optimal solution. Results from the analysis show that peak-valley tariffs increase cost-savings for prosumers and consumers at the expense of grid revenue.
The interaction between peak-valley tariffs and distributed trading is studied. A dynamic programming model is evaluated based on Fujian electricity market of China. TOU tariffs increase cost-savings for prosumers, albeit a weak peak-shaving effect. The value of PV declines when deployment increases linearly with storage.
