Problems solved by technology

The environmental protection of multi-energy grid connection is achieved by promoting the consumption of new energy, reducing network losses, or promoting energy efficiency, energy conservation and emission reduction on the demand side through efficient interaction; at the same time, with the construction of UHV power grids, the environmental protection of the regional power system Changes usually have strong externalities, that is, they have a greater impact on air pollution outside the region, which makes it difficult to stratify environmental protection

Abstract

The invention discloses a smart city multi-energy combined supply comprehensive regulation and control method and system, and the method comprises the steps: collecting the current operation parameterdata of a regulated and controlled smart city, and determining an index value in combination with a preset layered index model; determining an optimal index weight based on the index value; and regulating and controlling the regulated and controlled smart city multi-energy combined supply based on the optimal index weight. According to the technical scheme of the invention, the objective fairnessof evaluating the multi-energy coordination capability of the smart power grid demonstration project is considered, and a new comprehensive regulation and control method is provided from the aspectsof economy, environmental protection, safety and reliability.

Description

technical field [0001] The invention belongs to the field of comprehensive energy systems, and in particular relates to a comprehensive control method and system for multi-energy joint supply in a smart city. Background technique [0002] The realization of the goal of multi-energy coordination depends not only on the technical level of the whole network regulation and operation with the multi-level energy comprehensive coordination technology as the core, but also on the grid-friendly distributed power technology, distribution automation technology, various interactive technologies and other power sources. The application of relevant technologies on each side of the power grid and load will be introduced separately below. [0003] (1) Multi-level energy comprehensive coordination technology [0004] Multi-level energy comprehensive coordination technology is the core of smart grid multi-energy coordination. By making full use of various distributed power sources, micro-gri...
