Joint Optimization of Heat and Power Supply
In some cases, Combined Heat and Power (CHP) systems are only partially utilized for power generation. However, the primary objective of CHP systems is to use excess heat for heating users and to generate electricity through combined heat and power optimization. For the economic efficiency of centralized power generation systems, the utilization of heat energy is never the primary goal. The main reason for considering the use of CHP systems here is that they can significantly reduce carbon emissions and increase overall power generation efficiency. With the use of CHP systems, overall power generation efficiency can be raised from 33% of traditional thermal power technology or 50% of combined cycle gas turbines (CCGT) to over 80%. CHP is the core of microgrid economics, achieving maximum energy utilization efficiency by minimizing heat transfer losses between power generation units and loads. Therefore, CHP power generation units should be located near heat load sites. 36V aviation power supply, 400HZ frequency conversion power supply, 115/200V power supply, 27V DC power supply, 400HZ power supply, aviation power supply
2. Supply and Demand Joint Optimization
Joint optimization of supply and demand is the second priority for microgrid economics. Traditional electricity economics needs to be extended to the microgrid. In the scale economy of the main grid, load control is addressed in the analysis and planning stages through demand-side management, load shedding, interruptible tariffs/contracts, and other means. For microgrids, the key criterion for evaluating this joint optimization is the marginal cost of self-generated electricity at any given time point. In terms of generation economics, investment cost recovery, cross-subsidies, and non-metered and billed costs are not considered. In the scale economy of the main grid, factors such as costs and the environment are not well reflected. For microgrids, process optimization is relatively easier to achieve because producers and consumers are under the same decision-maker.
