Abstract

The invention relates to a single-pot electric energy storage device which comprises an energy storage pot body, a heat storage medium inlet, a heat storage medium outlet, an energy releasing medium inlet, an energy releasing medium outlet, an electric heater, an electric heater connector and an energy utilization device. The energy storage medium inlet is formed in the top of the energy storage pot body, and the heat storage medium outlet is formed in the bottom of the energy storage pot body. The energy releasing medium inlet, the energy releasing medium outlet and the electric heater connector are formed in the energy storage pot body, wherein the energy releasing medium inlet is located below the energy releasing medium outlet. The electric heater is arranged on the bottom inside the energy storage pot body, and the energy utilization device is connected between the energy releasing medium inlet and the energy releasing medium outlet in series. According to the single-pot electric energy storage device, on the one hand, the utilization efficiency of wind power and photovoltaic power generation is improved; on the other hand, the peak and valley problem of a power grid is solved, the problem that urban pollution is serious is solved, and the electric energy utilization efficiency of wind power and solar photovoltaic power generation and the power grid is improved.

Description

Technical field

[0001] The invention relates to the technical field of effective utilization of wind power / photovoltaic power generation and grid valley electricity, and in particular to a single-tank energy storage device for wind power / photovoltaic power generation and grid valley electricity and a use method thereof. Background technique

[0002] Smog has enveloped China, energy shortage and environmental pollution have become unprecedented challenges facing my country, and the development of renewable energy is a strategic national policy of my country. In July 2012, my country issued the "Twelfth Five-Year Development Plan for Renewable Energy". By 2015, my country's grid-connected wind power and solar capacity will reach 100 million kw and 15 million kw, respectively; by 2020, wind and solar grid-connected installed capacity Reached 200 million kw and 50 million kw respectively. However, the inherent intermittency and volatility of renewable energy such as wind and solar en...
