With the global energy reform, the energy storage field has become one of the current research hotspots. This paper considers the distributed phase change material unit (PCMU) system. First, the distributed PCMU model and the photovoltaic and energy storage systems model are constructed.
Data from the National Energy Administration shows that as of September 2023, the cumulative installed capacity of distributed household PV reached 105 million kilowatts, with 32.977 million kilowatts newly installed, and the cumulative number of households installed exceeded 5 million [1].
Abstract: Due to substantial uncertainty and volatility, photovoltaic (PV) power generation is often paired with a battery energy storage (BES) system to generate electricity, especially in a low-voltage distribution system. This paper proposes an integrated optimal control system for a household PV-BES system. The PV-BES system can feed the local load, sell the excess …

In 2023, the newly added grid-connected capacity of PV power generation in China was 216.30 GW. Among them, the newly added grid-connected capacity of distributed PV was 96.29 GW, while the installed capacity of household PV in the newly added distributed PV reached 43.48 GW (National Energy Administration. 2024).
The survey shows that in 2020, the number of household solar energy storage installations in Europe has increased by 44% to 140,000. This marks the first time that Europe has installed more than 100,000 household energy storage systems within 12 months, setting a new milestone for the European energy transition.

The total energy capacity of decentralized storage systems is estimated to amount to 600 MWh, with an installed power of 280 MW peak in Germany. [ 1, 2] In the years from 2010 to 2012 the average additional installed power of PV installations was still around 7–8 GW per year, before it dropped to 1.2 GW in 2014.
To achieve the maximum economic and technical benefits for households, it is important for grid-connected houses to select the optimal capacity of PV and BES which is considered a major problem.
Several parameters were integrated into the model in order to ensure an optimal sizing of the storage system. The results show that this approach minimizes the cost of the energy storage system and can be used to optimally size an ESS for a household, which has a rooftop grid-connected PV system.
The latest data released by the National Energy Administration showed that in 2021, the new installed capacity of household PV reached 21.6 GW, accounting for 73.8 % of the new installed capacity of distributed PV [14].
