Photovoltaic energy storage joint operation

Can pumped storage units com-pensate the changes of wind power and photovoltaics?

In this paper, pumped storage units are used to com-pensate the changes of wind power and photovoltaics, so as to achieve the purpose of shifting peaks, responding to wind power climbing, reducing the harm of new energy grid connection, and stabilizing the output of thermal power units.

How to promote the power system to consume wind power and photovoltaic?

In order to promote the power system to consume wind power and photovoltaic, a lot of research has been conducted by international scholars on the coordination mechanism of multi-source combined systems, multi-objective optimization of new energy units, and control strategies of integrated energy systems.

What if wind power and photovoltaic power are combined?

When the wind power and photovoltaic power are taken to the maximum value of the interval, the comprehensive cost of the combined system is the highest, that is, the worst scenario. The above formula can be rewritten as formula (25): ary of the interval, and the photovoltaic uncertain variable is the same.

Do photovoltaics and wind power have a good complementarity?

Wind power and photovoltaics usually have good complementarity on the hourly scale, and their total power generation can alle-viate the reverse peak regulation of wind power generation. The optimization results of the traditional unit combination model depend on the prediction accuracy of new energy output.

How can pumped storage and new energy units promote energy consumption?

The combined operation of new energy units and pumped storage units provides an effective strategy to promote system consumption of renewable energy (RER) and enhance the con-trollability of the power system [2, 3].

What is the optimal scheduling strategy for wind-photovoltaic-fired-pumped storage co-generation systems?

The literature proposed a two-stage optimal scheduling strategy for wind-photovoltaic-fired-pumped storage co-generation systems with the objectives of minimizing generalized load fluctuations and maximizing combined system power generation.
