Key words:

Recently, the "New Energy System Planning, Dispatch, and Visualization Platform Based on Multi-Energy Complementarity", jointly developed by Sitech and Beijing Institute of Technology, has commenced implementation within relevant projects of China Three Gorges Corporation. The platform has now been fully deployed and entered the trial operation phase. Addressing pain points such as insufficient source-load interaction, extensive planning and dispatch, and inadequate multi-energy coordination, this platform integrates Sitech's 19 years of industry expertise with university research achievements to create a comprehensive "Energy Brain" that offers "clear visibility, accurate calculation, and reliable control." This marks another significant milestone for Sitech in the field of green and smart energy.

01. Five Scenarios Interconnected, Driving Multi-Energy Coordinated Optimization

This project focuses on five typical research scenarios: residential areas, office areas, zero-carbon parks, hospitals, and data centers. It has established a refined mathematical model library covering over 30 types of key equipment across the source, supply, storage, and load sides. The project has already comprehensively completed the precise characterization of the dynamic characteristics and energy consumption patterns of cold, heat, and electricity loads in each scenario. It has also established mathematical models for the operational constraints and energy-mass balance of key equipment, laying a solid model foundation and data support for the subsequent optimal design and intelligent dispatch of the multi-energy complementary system.

Simultaneously, the platform innovatively constructs a comprehensive "Energy-Economy-Environment" (3E) evaluation system. Using energy efficiency, cost, and carbon emissions as core indicators, it precisely matches the high-reliability and low-carbon requirements of scenarios like zero-carbon parks and data centers, while also accommodating the economic demands of office buildings and residential areas. This drives high-energy-consumption scenarios to increase their green electricity ratio, promoting the efficient, economical, and green synergistic development of the energy system.

02. Three Innovative Breakthroughs, Building the Smartest "Energy Brain"

To solve the challenge of heterogeneous energy flow coordination within the project, the R&D team proposed a "Multi-Energy Complementary Energy System Architecture for Heterogeneous Energy Flows Coupling Multiple Conversion and Storage Devices."

This achievement is based on research into the cooling, heating, and electricity consumption characteristics of computing infrastructure. Combining principles of cascade energy utilization, multi-energy complementarity, and source-load interaction, it constructs a full-chain technical system covering generation, storage, and consumption. It establishes multi-dimensional mathematical models for new energy generation, traditional energy conversion, energy storage devices, and end-use equipment, achieving deep coupling and system synergy among diverse energy devices.

Digital Base for Heterogeneous Energy Flow Coupling: 30 Types of Equipment Mathematical Models

Based on principles like cascade energy utilization, multi-energy complementarity, and source-load interaction, and incorporating the latest domestic and international research, mathematical modeling has been conducted for over 20 forms of generation and consumption (including PV, wind power, solar thermal collection, biomass power generation, waste-to-energy, charging piles) and a total of 30 types of storage equipment (including thermal storage, cold storage, electrochemical energy storage, compressed air energy storage). Attributes such as efficiency, response time, and power are converted into mathematical models, enabling rapid deployment through parametric encapsulation, providing a high-precision simulation foundation for the collaborative optimization of energy flow target analysis and the master control communication module.

Decision Engine for Multi-Objective Collaborative Optimization: Energy Flow Target Analysis
Energy planning is the starting point for building a comprehensive energy system. By establishing multi-energy simulation models and a multi-objective optimization framework, combined with source-grid-load-storage multi-energy complementarity algorithms, it balances five core objectives: minimizing annualized cost, maximizing exergy efficiency, optimizing comprehensive energy efficiency, minimizing carbon emissions, and maximizing clean energy consumption.

Neural Center for Cross-Platform Collaboration: Master Control and Communication Module
Addressing issues like complex energy device protocols and data silos, Sitech adopts a design philosophy of "highly compatible protocols":

Protocol Adaptation: Supports industrial protocols such as Modbus, IEC104, compatible with over 90% of mainstream devices.

Independent Architecture: An integrated design ensures system autonomy, capable of millisecond-level data acquisition and cross-platform transmission.

03. Four Functional Modules, Creating a New Visual Energy Management Experience

This visualization platform integrates systems such as PV inverters, simulators, and smart gateways. Through four functional modules, it makes complex energy management intuitive and efficient.

Panoramic Energy Flow Precision Control:
Displays time-shared output, energy storage charging/discharging, and energy prices globally. Visually tracks multi-energy flows and quickly locates high energy consumption points.

Multi-Energy Synergistic Dynamic Optimization:
Adjusts multi-energy output strategies in real-time based on seasonal and hourly parameters, balancing energy efficiency, stability, and economic goals.

Intelligent System Capacity Planning:

Leverages mixed-integer programming and intelligent algorithms to accurately calculate equipment capacity and optimize annual energy supply plans, enhancing overall system efficiency.

Precise Tracing of Energy Efficiency Losses:
Based on the heterogeneous energy flow architecture, analyzes equipment output and energy storage status, identifies loss paths, and supports refined energy efficiency improvements.

With the successful deployment of Sitech's "New Energy System Planning, Dispatch, and Visualization Platform Based on Multi-Energy Complementarity" within the Three Gorges project, energy planning is transforming from an experience-dependent "art" into a data-driven "science." Looking ahead, Sitech is committed to productizing and standardizing this platform's capabilities, empowering more parks and cities to achieve precise energy planning and low-carbon transformation. This allows every project to find its own optimal solution even before construction begins.
