Development Trends Of Future Power Systems

Modern power systems have evolved into large interconnected systems composed of high-temperature, high-pressure, supercritical, and ultra-supercritical generating units, along with large-capacity long-distance transmission networks and continuously varying loads. These systems are currently the largest and most complex man-made systems in the world, characterized by wide geographic distribution, massive energy transmission, and complex dynamic processes. Their mathematical models exhibit high dimensionality, strong nonlinearity, and time-varying characteristics.

The development trends of modern power systems are mainly reflected in the following eight aspects:

The main development trend of modern power generation units is high-efficiency, low-pollution, and low-energy-consumption power generation equipment characterized by high temperature, high pressure, and supercritical technology, along with new clean coal combustion power generation technologies, which have become the focus of development. Specifically, this is reflected in: ① Rapid development of large-capacity, high-efficiency gas turbine power generation units; ② Air-cooled power generation units and combined heat and power units are moving toward large-scale development; ③ The level of automation in unit operation is continuously improving.

Developing large power grids and implementing interconnection among regional power grids offer the following advantages:

① Reducing the total installed generating capacity required in the system;

② Enabling large power grids to accommodate large-capacity thermal power units, which helps lower construction costs and save energy;

③ Making full use of energy resources and allowing more economical dispatch of hydropower and thermal power over a wider area;

④ Using energy resources more rationally by transmitting electricity instead of transporting coal;

⑤ Allowing different regions to share power resources and serve as mutual backups, thereby enhancing the ability to withstand accidents, improving grid security, and increasing the reliability of power supply;

⑥ Enabling large power grids to withstand greater disturbances, which helps improve power quality.

The power grid dispatch automation system is an important means to ensure the safe, high-quality, and economical generation and supply of electricity, and to improve the level of power grid operation management. It is a crucial foundation for the automation of power production and the modernization of management. With the further deepening of reforms in the electric power industry and the ongoing exploration of the electricity market, new requirements are continually being put forward for power grid dispatch automation. The connotation of modern power grid dispatch automation systems is also continuously expanding and developing. It not only includes energy management systems, distribution network energy management systems, automatic power measurement systems, and hydropower dispatch automation systems, but will also encompass relevant aspects of technical support systems for the electricity market.

Electricity marketization refers to establishing a market mechanism for equal competition in the electricity industry. A market economy is a competitive economy, so reforming the electricity system involves creating a market-based operational mechanism with equal competition. Within the broader framework of a market economy, and according to the development needs of the electricity industry, a scientific, fair, just, and orderly competitive environment for the electricity market should be gradually optimized while ensuring national electricity security. This includes establishing a bidding mechanism for power generation companies to sell electricity to the grid and a competitive sales mechanism for power grid companies in transmission, distribution, delivery, and retail of electricity products.

The global energy interconnection is a robust, intelligent power grid with ultra-high voltage (UHV) networks as its backbone and global interconnections. It is the foundational platform for large-scale development, allocation, and utilization of clean energy worldwide, essentially embodying "smart grid + UHV grid + clean energy."
