The integrated energy service is a new form of service for diversified energy production and consumption. That is, on the basis of traditional multiple energy supplies (electricity, gas, hot and cold) to integrate renewable energy, storage facilities and electrified transportation etc., through the combined supply of electricity, gas, heat and cold, distributed energy and micro energy grid etc., rely on Big Data, Cloud Computing, Internet of Things, Mobile Internet, Artificial Intelligence and other technologies to realize multi-energy coordinated supply and comprehensive energy utilization. It is a new energy service mode to improve the efficiency of energy system and to reduce cost.
The Platform for Integrated Energy Service (PIES) provided by XD, provides customized integrated energy service solutions for energy supplier, regional energy companies, industrial/business parks and large industrial and mining enterprises.
(1)System Architecture
PIES system is developed based on the DYNAS platform of XD composed of supporting platform, application system and connecting platform as well as the buses for information exchange.
● Supporting Platform: Provide platform services, front-end framework software tools and other software modules;
● Application System: Composed of many business units including marketing, distribution networks, energy consumption, energy sales and other components, can be flexibly configured according to the requirements of application scenarios.
●Information exchange bus: cutting-through the application systems and the supporting platform, interact data with various application systems.
(2) System function characteristics
● Flexible Solution to Various Applications
PIES is an integrated system platform of multi-energy, multi-data and multi-service, and is customizable for multiple target users with different business portfolios.
● Integrated Management and Control for Operation, Distribution, Consumption and Sales
PIES creates an integrated energy service system that integrates operation, distribution, consumption and sales, includes electricity distribution, marketing and sales, four tables in one, customer service, efficiency management and other businesses. At present, these businesses are independently implemented from each other in China’s power grid, integrated application covering operation, distribution, usage and sales has not been carried out on a large scale, and there are few related products. Along with the electric power system reform unceasingly thorough, the demand for the integration of operation, distribution, utilization and sales and the comprehensive control of regional energy resources is taking shape. PIES integrates services of operation, distribution, utilization and sales into a unified platform, to realize comprehensive control of the business process.
● Plug and play for Distributed Energy
PIES supports wind/light power generation, micro grid, energy storage, charging piles and other distributed energy access. The management to distributed power supply and micro grid are used to predict short-term and ultra-short-term power generation of the system, control parallel-in and off-grid operation of micro-grid and the power exchange between the distribution network of the micro-grids; The management to the equipment of energy storage, charging and discharging is used to manage the orderly operation of batteries, electric vehicles etc. in the area.
● Multi-energy Complementary and Optimal Scheduling
Faced to the multiple energy requirements of electric power, thermal energy, cold and gas of the user, complementary use of both traditional and new energy sources, through the modes of multiple supply of heat, electricity, cold and gas, distributed renewable energy and smart micro grids and so on, to realize multi-energy coordinated supply and comprehensive cascade utilization of energy.
● Coordination Control of Source, Net, Load and Storage
Based on the real-time monitoring to the running state of the equipment of distribution network, distributed power sources and micro-grids, and based on economic operation or emergency, interactive control is carried out on relevant equipment of source, network, load and storages storage, to ensure the safe, reliable and economical operation of distributed power supply after it is connected to the distribution network.
● Intelligent Operation and Maintenance in the Full Life Cycle
The intelligent operation and maintenance is used to achieve the operation and maintenance management of primary and secondary distribution equipment, management the maintenance of water, gas, heat and other energy, including status monitoring of the equipment within their life cycle, fault diagnosis and treatment, maintenance management, inspection process management, as well as the asset management and so on.
