A smart grid, an information system

A smart grid, an information system with a massive amount of data, is challenging to dispatch loads directly. Therefore, a grid system that can integrate resource information, a load aggregator that can meet the power demand on the user side, and the primary users of electric power consumption is considered. According to the above analysis on the user-side DR flexibility in the power information system, the load aggregator is chosen as the research subject. The new information energy’s incentive electricity price is applied to construct the smart grid’s information dispatch strategy. In this distributed smart grid information dispatch framework, the fundamental structural layers are smart grid information dispatch, aggregator decision-making, and load response. The primary role of smart grid information dispatch aims to issue information dispatch tasks. In smart grid systems, distributed new energy and interconnected grid transmission are the principal ways to obtain electric power. The aggregator decision-making layer aims at the interaction between the power grid information system and users and dispatches the dispatchable capacity and plan in the information system. The load response layer can receive information dispatch signals, which depends on intelligent information terminals to collect electricity consumption information. Its principal function is to implement dispatch tasks. Information dispatch includes day-ahead dispatch and real-time dispatch. The former is cleared before the day, and the latter is cleared every hour. On this basis, the implementation process of information economic dispatch under this multi-period is shown in Figure 2 below.
