 1.2 Overall Design of the Project Plan


This project is an off-grid system that integrates solar energy and diesel power. The system is not connected to the power grid and is configured with a combined power supply from solar storage and diesel generation. The system includes a 500 kW solar storage unit equipped with 720 kWp of photovoltaic modules, which are connected to 12 sets of 60 kW MPPT modules through 12 photovoltaic lightning protection combiner boxes. After boosting or bucking, the MPPT modules connect to the energy storage batteries on the DC bus. The system then inverts, isolates, and filters the power to supply pure sine wave AC electricity to mechanical equipment in conjunction with diesel generation. This project utilizes EasySmart EMS to coordinate and control the entire solar storage and diesel system. By collecting and reading electrical performance parameters of the solar storage system, diesel generator system, and electrical loads, it optimizes the operation of each subsystem according to preset working modes, achieving intelligent operation and maintenance of the entire system. The system schematic is as follows:

 1.3 Overview of EMS Control Strategy for Biomass Energy Storage System


During the system power supply process, the diesel generator has been in operation. In the presence of sufficient sunlight during the day, it prioritizes solar energy usage, with excess photovoltaic energy stored in the battery pack. The insufficient load power is supplemented by the diesel generator. At the same time, the diesel generator and energy storage work together to supply power to the load. The energy storage system mainly adjusts the instantaneous impact load or independently handles low power load rates, allowing the diesel generator to operate in the optimal efficiency mode, which can save over 30 % 30 % 30%30 \% in generator fuel costs.

 2. Configuration of Photovoltaic Modules


This project’s 500kW solar storage integrated machine is equipped with 12 60 kW MPPT controller modules, allowing for a maximum of 720 kWp photovoltaic input. The project plans to build a 720 kWp photovoltaic power generation system (when sunlight is good, if the photovoltaic power generation exceeds the maximum allowed photovoltaic capacity input of the MPS, the MPPT will automatically limit the power input). Considering the battery cluster voltage range of 211.2 kWh for this project is set to 616 V ∼ 792 V 616 V ∼ 792 V 616V^(∼)792V616 \mathrm{~V}^{\sim} 792 \mathrm{~V} , the MPPT module operating mode is set to "boost mode."
 "The configuration principles are as follows:"

Boost mode: Under extremely low temperature conditions, the MPPT open-circuit voltage should be above the minimum battery operating voltage of 30 V.

 4. Structure and Composition of the Container System


The 500kW/1056kWh energy storage system adopts a prefabricated integrated design, with a solar storage integrated machine (MPS), lithium iron phosphate battery, battery management system (BMS), gas fire protection system, thermal management system, and auxiliary power distribution all integrated within a 20-foot container. The system has a high degree of integration and strong environmental adaptability, effectively reducing the workload for on-site installation, debugging, and later maintenance.

The energy storage system uses lithium iron phosphate battery packs as the energy storage medium. The energy storage system connects the energy storage batteries to the battery input side of the solar-storage integrated machine (MPS) after passing through a high-voltage box. Each battery pack is equipped with a battery management system (BMS) for online management of the battery's charging and discharging, and the BMS is connected to the MPS to execute charging and discharging control strategies.

 4.1 Introduction to Containers


The containerized energy storage system is designed using a standard 20-foot container, making it convenient for transportation and installation, and multiple container systems can be combined to increase energy storage capacity according to actual needs. Different specific configuration methods are used to ensure the stable operation of the container energy storage system in various application scenarios.

This project’s container energy storage system is applied in Gabon, Africa, using a standard 20-foot container, supporting overall transportation. The complete solution from Yisite includes a liquid-cooled lithium iron phosphate battery system, a fire protection system, a temperature control system, etc., all installed inside the container, forming an integrated diesel-solar storage microgrid system. This product features high energy density, long lifespan, safety and reliability, and a wide range of applications, making it an ideal energy storage product for the industrial and commercial energy storage and smart microgrid industries.
 Container external dimensions: 6058 × 2438 × 2896 m m 6058 × 2438 × 2896 m m 6058 xx2438 xx2896 mm6058 \times 2438 \times 2896 m m .

 4.2 Fire Protection System


The fire suppression system in the container uses heptafluoropropane (or perfluorohexanone) as the extinguishing agent, which primarily relies on chemical suppression while also having physical suppression properties. It is colorless, odorless, clean, non-conductive, and does not contaminate the protected objects. It will not damage property or precision equipment and has no harmful effect on the atmospheric ozone layer (with an ODP value of zero), meeting environmental protection requirements. In most protected areas, the extinguishing concentration is below the non-toxic reaction concentration for humans (NOAEL concentration), making it safe for human exposure. It is an excellent clean gas fire extinguishing agent. The fire protection system is designed to be sensitive and reliable, ensuring active fire protection functions. The system consists of smoke detectors, heat detectors, audible and visual alarms, and a gas extinguishing system.

 4.3, Container System EMS Configuration


The energy storage EMS system consists of two parts: a 10.1-inch monitoring display and the Little Sun cloud platform. The 10.1-inch monitoring display integrates control and display, responsible for data collection and strategy execution of the solar storage system, acting as the local EMS backend to achieve local data visualization and local configuration of MPS device parameters. The Little Sun cloud platform serves as the remote EMS backend, enabling remote monitoring of data and remote setting of MPS device parameters.

 4.3.1 Data Collection


The EMS data collection device with a 10.1-inch display is responsible for the collection and analysis of data from related equipment. The devices are generally divided into fieldbus interface devices and non-intelligent interface (dry contact signal) devices. For devices connected via Ethernet, a configurable switch can interconnect the EMS controller and various network devices; for devices connected via RS485, they can be cascaded in a daisy chain manner and then connected to the EMS controller; for devices connected via dry contact, such as fire alarms and smoke detectors, they connect to the EMS controller through dry contact signal lines.
 4.3.2, Cloud Monitoring (Photovoltaic Storage System)

If you want to achieve the convenience of remote access to the EMS system, the following methods can be implemented: The EMS data collection device is equipped with a 4G communication module, which has the capability to distribute data to multiple backends. It uploads data to the local 10.1-inch monitoring display backend while also sending data to the energy storage EMS cloud platform, Little Sun Cloud Platform. With the existing cloud infrastructure, cloud monitoring can be quickly realized, and the relevant data interface of the cloud platform is as follows. You only need to insert a local 4G SIM card into the EMS data collection device to upload the data to the cloud.

 5.3, Principle of Integrated Light Storage Machine

The topology of the integrated solar energy storage system is shown in the figure below. The system can be divided into three parts: the DC/DC conversion side, the DC/AC conversion side, and the DC bus. The low-voltage side of the DC/DC converter consists of independent modules, each using a non-isolated unidirectional DC/DC conversion topology, which can be directly connected to photovoltaic and energy storage units and can perform constant voltage/constant current control as needed. The DC/AC conversion side adopts a two-level three-phase full-bridge topology, which connects the AC side to the grid for power control during grid-connected operation, and performs constant voltage and frequency control during off-grid operation to provide a stable AC power supply for the load. The high-voltage side of the DC/DC conversion in the integrated solar energy storage system is connected to the DC side of D C / A C D C / A C DC//ACD C / A C through the DC bus, and the stability of the DC bus voltage directly affects the stability of the system.

 6. Strategy EMS Configuration for the Chai Guang Storage System (Central Control)


This project is equipped with an EasyStar EMS for the control and coordination of the photovoltaic-storage-diesel power supply system. This EMS communicates with the MPS using the MODBUS communication protocol based on the MPS standard provided by EasyStar, and the MPS operates under the scheduling of the EMS.

During the system power supply process, the diesel generator has been in operation. In the presence of sufficient sunlight during the day, it prioritizes solar energy usage, with excess photovoltaic energy stored in the battery pack. The insufficient load power is supplemented by the diesel generator. At the same time, the diesel generator and energy storage work together to supply power to the load. The energy storage system mainly adjusts the instantaneous impact load or independently handles low power load rates, allowing the diesel generator to operate in the optimal efficiency mode, which can save over 30 % 30 % 30%30 \% in generator fuel costs.
