Against the backdrop of increasing global demand for energy and environmental concerns, demand-side management (DSM) has gradually become a key solution. Demand-side management refers to adjusting consumers' energy demand through a variety of means, including financial incentives and behavioral changes. The goal of this strategy is to reduce energy consumption during peak demand periods or to shift energy use to off-peak times, such as at night or on weekends.
"Demand-side management not only reduces energy costs, but also reduces reliance on traditional energy generation, which is an important step in the transition to renewable energy."
Under the influence of energy demand management, electricity markets in many countries have begun to adapt to this emerging concept. Especially after the energy crises in 1973 and 1979, the concept of DSM was gradually recognized and implemented, becoming one of the policies strongly promoted by governments.
The U.S. power industry has long relied on external energy until the 1980s, when, due to the impact of the energy crisis, the government enacted the Public Utility Regulatory Policies Act (PURPA) to encourage energy efficiency and alternative energy. Today, the development of information technology has made DSM technology increasingly mature, and concepts such as smart grid and integrated demand side management (IDSM) have been widely used.
"By integrating demand-side management, electricity consumers can adjust their electricity consumption based on real-time price signals, further improving the matching of supply and demand."
From the perspective of market and government actions, the core of energy demand management is to influence consumers' energy demand. In the past, due to the continuous supply and low cost of energy, increasing electricity consumption has become a general trend, but the problem is that energy prices continue to rise, which requires companies to seek new strategies to reduce demand.
Use less electricity to accomplish the same tasks, such as choosing energy-efficient appliances. Such measures usually involve long-term demand reduction.
2. Demand responseThis refers to consumers actively changing their electricity usage behavior based on the status of the power system, including adjusting electricity usage time and limiting electricity usage.
The operation cycle of appliances can be moved forward or delayed by a few seconds to match the real-time needs of the power grid, and such adjustments are almost imperceptible to end users.
Small, decentralized power generation and storage devices allow for more flexible management of different energy sources and reduce environmental impact.
Demand-side management can be divided into national level, public utility level, community level and household level. No matter at which level, it will ultimately affect the balance between demand and supply.
Achieve nationwide energy efficiency improvements through legislation and standard setting.
2. Utility GradeDuring periods of peak demand, for example, utilities can control equipment such as water heaters, swimming pool pumps and air conditioners to reduce load.
Communities can leverage their collective purchasing power to work together to improve energy and electricity efficiency.
More and more homes are installing solar energy systems, providing individuals with the opportunity to reduce their reliance on the grid.
In Queensland, utility companies are able to remotely control household appliances and incentivize users to use electricity during off-peak hours to reduce overall demand. Similar examples are emerging in Toronto, Indiana and Brazil, and learning and innovation are growing everywhere.
Potential Challenges"From the two-way adjustment of supply and demand, demand-side management can not only improve the overall efficiency of the power supply system, but also help reduce carbon emissions."
For example, requiring consumers to adjust their electricity usage behavior based on peak and off-peak electricity prices may face challenges with high costs and low acceptance. However, with the continued energy crisis and increasing awareness of environmental protection, demand-side management practices are gaining more and more attention.
In the future, can demand-side management truly become the key to solving global energy problems?
