现场能源生产被称为分布式能源（DER），为消费者提供了许多好处，例如节省账单和可预测性，提高系统效率，提高可靠性，控制电能质量，以及在许多情况下，更环保的电力。此外，DER系统可以通过减少电网拥堵，减少对新发电和输电容量的需求，并提供电压支持和紧急需求响应等辅助服务，使电力公司受益。分布式能源（DER）的本地聚合可以包括对现场终端使用能源设备的主动控制，可以称为微电网。微电网需要控制，以确保安全运行，并作出调度决策，实现系统目标，如成本最小化，可靠性，效率和排放要求，同时遵守系统约束和监管规则。该控制由能量管理器（EM）执行。优选地，EM将实现合理地接近可达到的最佳的操作，它将通过对与预期条件的偏差鲁棒的手段来实现这一点，并且它本身将不会招致不可支持的资本或操作和维护成本。此外，微电网可以包括对最终用途的监督，例如削减或重新安排某些负载。通过将统一的微电网视为一个供需系统，而不仅仅是一个现场发电设备系统，可以利用综合供需控制的好处，例如经济节约和提高系统能效。
On-site energy production, known as distributed energy resources (DER), offers consumers many benefits, such as bill savings and predictability, improved system efficiency, improved reliability, control over power quality, and in many cases, greener electricity. Additionally, DER systems can benefit electric utilities by reducing congestion on the grid, reducing the need for new generation and transmission capacity, and offering ancillary services such as voltage support and emergency demand response. Local aggregations of distributed energy resources (DER) that may include active control of on-site end-use energy devices can be called microgrids. Microgrids require control to ensure safe operation and to make dispatch decisions that achieve system objectives such as cost minimization, reliability, efficiency and emissions requirements, while abiding by system constraints and regulatory rules. This control is performed by an energy manager (EM). Preferably, an EM will achieve operation reasonably close to the attainable optimum, it will do this by means robust to deviations from expected conditions, and it will not itself incur insupportable capital or operation and maintenance costs. Also, microgrids can include supervision over end-uses, such as curtailing or rescheduling certain loads. By viewing a unified microgrid as a system of supply and demand, rather than simply a system of on-site generation devices, the benefits of integrated supply and demand control can be exploited, such as economic savings and improved system energy efficiency.
