Dispatch
There is a dispatch to achieve the most economically viable operational plan in a power plant. This calculation includes the variable costs of each power plant (such as the cost of fuel in a coal power plant) along with projected prices in energy markets. A power plant only operates if its variable costs are less than the guaranteed selling prices. Dispatch creates a schedule when it determines the allocation of available capacity to factories or power plants. Invoices include location (which factory will be used?), Time (how long has the factory been used and since when?) And graduation (should the factory be part-time or full-time?).
Power plant operators are usually required to register their program with the relevant transmission network operator in order to be able to predict the power available in the network.
Dispatch is also used in the field of renewable energy. Oscillation operators evaluate renewable energy, such as solar and wind energy, weather forecasts, and plant availability to determine the next day’s schedule. Controllable renewable energy operators create multi-day plans for their assets, which may include biomass and hydropower plants. This allows the operator to base resource allocation on energy exchange prices.
Redispatch
Redispatch is mainly used in areas such as California or Germany with a high proportion of renewable energy production. It is less seen in other areas. To re-understand rescheduling, consider how power plants send their applications to transmission system operators, as mentioned earlier. As soon as they receive the plans, the network operators do what is known as network load flow or load calculation to prepare an overview of the expected network feed and consumption for the next day. They analyze the transmission to determine if part of the grid may be adversely affected and to what extent. To minimize the number of short-term interventions and stabilize the grid the next day, the transmission system operator can instruct power plant operators to delay planned power generation based on the next day’s load flow calculation to avoid grid bottlenecks. The request to change the power generation is called a resubmission.
