High penetration wind power grid with energy storage system can effectively improve peak load regulation pressure and increase wind power capacity. In this paper, a capacity allocation method of energy storage system under peak load regulation scenario is proposed. The upper model combines the investment cost, operation cost, arbitrage income, environmental income, and wind power grid benefits during the entire life cycle of the energy storage system, with the goal of maximizing the net income during the energy storage life cycle; the lower model optimizes the charging and discharging power of the energy storage system according to each energy storage configuration scheme in the upper modeling, and its objective is to minimize the standard deviation of system net load and waste wind power. Finally, under the conditions of local grid load and wind power data, verified the effectiveness of capacity allocation strategy.

Distributed generators (DG) exhibit output volatility, and their connection locations are unevenly distributed. The high proportion and large-scale integration of DG into low-voltage distribution networks can lead to voltage violations at line terminals and uneven feeder loads. In this paper, a flexible interconnection distribution network is constructed based on Intelligent Soft Open Points (SOP), where the operation modes of the flexible interconnection system are classified, the power transfer relationships are outlined, and the voltage violation mechanisms are analyzed. A multi-mode collaborative voltage control scheme for low-voltage flexible interconnection systems is proposed. The distribution network operation modes are classified based on the inherent voltage levels at the ends of each feeder and the load status of the main transformer. By integrating the internal energy storage system of the SOP, a multi-mode collaborative voltage control strategy based on SOP is proposed. This strategy can simultaneously manage voltage violations at the terminals of interconnected distribution lines and achieve load balancing control, with the flexibility to be applied to multi-terminal flexible interconnection scenarios. The feasibility and effectiveness of the proposed control strategy are validated through a simulation model of the constructed flexible interconnection distribution network.

Under the background of dual-carbon target and large-scale new energy access, most of the existing powersystem scheduling modes focus on the power source side, ignoring the potential of load-side interaction with the grid for peak shifting. In order to promote two-way coordination and interaction on both sides of the source and load sides, and to guarantee the balance of power supply and demand on different time scales and the high level of new energy consumption, it is proposed to incorporate the representative electrolysis aluminum loads on the load side into the main body of the scheduling, and to optimize the dispatching of power supply and demand through the configuration of It is proposed that the representative electrolytic aluminum load on the load side should be included in the main body of dispatch, and by configuring battery energy storage devices on the load side, joint optimal dispatch with thermal power units containing carbon capture devices should be carried out. With the optimization objective of minimizing the operating cost of the powersystem, a joint day-ahead-intraday economic dispatch method is developed. Finally, simulation calculations are carried out with an example to show that the proposed peaking model can effectively guide the demand response of the aluminum loads, increase the rate of new energy consumption, and reduce the operating cost of the system at the same time.

Under the background that countries all over the world constantly advocate energy conservation and emission reduction and seek to deepen the reform of powersystems and introduce new energy trading policies, this study constructed a carbon-oriented local integrated energysystem multi-energy coupling market architecture. This construct was aimed at problems that current multi-energy coupling market research has not considered, including multi-energy substitution characteristics and carbon emission factors. First, taking the local integrated energysystem as the main physical architecture, a multi-energy coupling market architecture was constructed combining the main market participants of different energy subsystems. Second, a model of the subsystem markets in the energy coupling market, and the joint clearing method were proposed. Finally, the guiding role of the energy coupling market was analyzed by simulation for reasonable pricing and carbon emission reductions of different energy market operators.
