AI Technical Summary

Technical Problem

The randomness and intermittency of photovoltaic power generation in existing technologies lead to the phenomenon of reverse peak shaving, resulting in energy waste. Furthermore, the peak shaving capacity is insufficient, making it difficult to effectively absorb new energy sources. The peak shaving capacity of the existing peak shaving ancillary service market is also limited.

Method used

We construct an optimized scheduling model for photovoltaic-storage systems that takes carbon revenue into account. By having photovoltaic power plants participate in grid peak-shaving ancillary services and combining the interaction and power transfer modes of energy storage systems, we optimize the control methods of photovoltaic-storage joint systems to maximize net revenue, including peak-shaving market revenue and carbon emission reduction revenue, while reducing energy storage scheduling and photovoltaic system operation and maintenance costs.

Benefits of technology

It has achieved stable absorption of photovoltaic power generation, improved the peak-shaving capacity of the power grid, maximized the revenue of photovoltaic-storage systems in the peak-shaving ancillary service market, and reduced energy waste and operation and maintenance costs.

Abstract

The application discloses a control method for a photovoltaic energy storage system participating in a peak regulation auxiliary service market considering carbon benefits, and establishes an optimization model with a target of maximum net benefits of a photovoltaic energy storage combined system in a peak regulation market, wherein the net benefits are compensation benefits minus operation costs of the combined system, the compensation benefits mainly include peak regulation benefits and carbon emission reduction benefits, and the operation costs include energy storage calling costs, photovoltaic system operation and maintenance costs and light abandonment punishment of the photovoltaic system. Constraint conditions of the constructed model include three aspects: power flow direction constraints of the photovoltaic energy storage combined system, charge and discharge power value constraints of the photovoltaic energy storage combined system and energy storage equipment state of charge constraints. The constructed model can be converted into a mixed integer linear programming model, and effective results can be solved by relying on a Cplex commercial solving software. The solved operation control mode can guide the photovoltaic energy storage combined system to realize maximum benefits in the peak regulation auxiliary service market.
