Hybrid power plants are an innovative solution for increasing and optimizing energy production, combining, as they do, hydropower, solar, wind, and storage systems.
The purpose of a hybrid power system is to produce as much energy from renewable energy sources to ensure the load demand. In addition to sources of energy, a hybrid system may also incorporate a DC or AC distribution system, a storage system, converters, filters and an option to load management or supervision system.
These systems consist of micro-hydro, solar, wind and Diesel generator and battery as back-up (Fig. 7.30) . Description of hybrid photovoltaic/wind//hydro/diesel system The role of a hybrid (fuel cell-PV) system is the production of electricity without interruption in remote areas.

The configuration of user-side energy storage can effectively alleviate the timing mismatch between distributed photovoltaic output and load power demand, and use the industrial user electricity price mechanis.
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.
The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation.
In order to further analyze the relationship between the user's annual comprehensive cost, photovoltaic installed capacity, and peak-to-valley price difference, different scenarios are set for comparative analysis. Under the current time-of-use electricity prices, change the installed capacity of photovoltaic.
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.
The factory parameters of energy storage refer to the data in, N 0 is set to 1591, and k p is set to 2.09. Power customers use energy storage “low storage and high release” arbitrage, and time-of-use electricity prices have a greater impact on the optimization results of energy storage operations.
When the benefits of photovoltaic is better than the costs, the economic benefits can be raised by increasing the installed capacity of photovoltaic. When the price difference of time-of-use electricity increases, economic benefits can be raised by increasing the capacity of energy storage configuration.
