Hydroelectric units can produce overproduction under the following circumstances:
1. Upstream water is abundant and there is a possibility of water abandonment. In order to maximize the use of water resources, this is necessary. to overproduce;
< p>2. Electricity consumption in the system is limited and hydroelectric units must increase their production during the peak period of electricity consumption;3. Electrical units cannot be connected to the system during the accident and lose significant electrical power. At that time, hydroelectric units are expected to exceed
4. dispatcher orders overproduction;
If residents don't use electricity at night, will the electricity provided by the power company be lost?
I haven't given up .
The meal must be eaten one bite at a time and the road must be traveled to the end.
Although in recent years, wind power has made alarming remarks about the difficulty of connecting to the grid, but with the increase in wind power deployment and adjustment of the national network, it is also be connected to the network step by step. The electricity network must go through an adjustment process. You can't install a wind turbine and immediately connect it to the grid. Today, the grid connection rate of wind energy has reached 60%, far exceeding the 20 to 30% five years ago. It's already very good. We have reason to believe that there will be more mergers in the next phase.
In terms of electricity generation model,
In addition to coal, these are wind, light, hydro and atomic energy. Today, with the exception of coal, the other four are all developing rapidly. It will only get better.
Understand firstthe characteristics of electrical energy products; one of them is that electrical energy products are generated, supplied and used instantly. There is no inventory of work in progress or finished products! The level of quality of electrical energy; production = supply + consumption, proportional generation of 100 kW = supply of 10 kW (overall loss) + consumption of 90 kW, overdrive or insufficient active power will directly affect the quality of electric power. Do residents lose electricity when not using it at night? There is a loss! But for primary energy loss, if hydropower is produced, 1. the trickle plant discharges water (water does not pass through the turbine to do the work), 2. the storage plant stores water, and if the tank is full, the water will be released due to overflow. It is the electricity production companyentity that loses hydroelectric power rather than the electricity supply company that loses electric power. To solve this problem, increasing the load factor is the most effective way, and implementing on-peak, on-peak, fixed and off-peak electricity tariffs is guaranteed to increase the load factor.
