Photovoltaik und Energiespeicher ist die perfekt Kombination um die Unabhängigkeit zu schaffen. Die effiziente Eigennutzung auch an bewölkten Tagen und Nachts des produzierten Solarstroms ist nur durch die Verbindung von Photovoltaik und Energiespeicher möglich. Unser Energiemanager überwacht den Strom, der von ihrer Photovoltaik Anlage

What is a bi-level optimization model for photovoltaic energy storage?

This paper considers the annual comprehensive cost of the user to install the photovoltaic energy storage system and the user’s daily electricity bill to establish a bi-level optimization model. The outer model optimizes the photovoltaic & energy storage capacity, and the inner model optimizes the operation strategy of the energy storage.

What is the energy storage capacity of a photovoltaic system?

The photovoltaic installed capacity set in the figure is 2395kW. When the energy storage capacity is 1174kW h, the user’s annual expenditure is the smallest and the economic benefit is the best. Fig. 4. The impact of energy storage capacity on annual expenditures.

What is a decision variable in a photovoltaic system?

The outer objective function is the minimum annual comprehensive cost of the user, and the decision variable is the configuration capacity of photovoltaic and energy storage; the inner objective function is the minimum daily electricity purchase cost, and the decision variable is the charging and discharging strategy of energy storage.
