Distributed Generation Smoothing Absorption Method Based on Power Internet of Things under Market Mechanism

With the increasing proportion of new energy sources such as wind and photovoltaics and the dispatchable potential of the demand response on the load side, distribution networks' characteristics have undergone great changes. Both the economic dispatch on the distribution network side and the demand response on the user side affect the electricity market's transaction process. On the one hand, economic dispatch will lead to changes in conditions, which will change power users' demand response strategy. On the other hand, users adjust the power demand to respond to maximum profits. And the results of demand response affect the load curve. Based on current technologies such as the Internet of Things, this paper takes the day-ahead market and the real-time market as the core on the time scale and uses a multi-objective optimization algorithm to optimize multiple indicators. In this process, an intelligent source load matching method considering the balance of multilateral interests is proposed. Finally, by introducing blockchain and smart contract technology, this paper guarantees information security during the transaction and can greatly improve the electricity market's real-time transaction efficiency.
