AGC-Dispatching-Häufigkeit des Energiespeicherkraftwerks

This paper presents a new real-time optimal mileage based dispatch (OMD) algorithm for a generating company (GenCo) responding to the automatic generation control (AGC) dispatch signals in real time in context of a performance-based frequency regulation market. Distinguished from traditional methods, the proposed method innovatively incorporates

What is AGC dispatching?

As presented above, the proposed AGC dispatching schemes requires constant information exchange between different components in the power network. Not only do they belong to different manufacturers but also different domains, e.g. generators, measurement units and electronic controllers. This requires a mutually comprehensible language.

What is the communication model for the proposed AGC dispatching scheme?

The communication for the proposed AGC dispatching scheme is designed according to IEC 61850. The communication model for generators is developed according to the IEC 61850 information model using the logical nodes defined in IEC 61850-7-420 standard . IEC 61850-7-420 information model for the generators is shown in Fig. 8.

What is AGC order dispatching ratio?

In the first case “Conventional”, AGC order dispatching ratio is set to the ratio of rated capacities of AGC units to simulate conventional system dispatching rule. In the second case “Offline (over40)”, dispatching ratio is optimized by offline method proposed in .

What is a proposed AGC?

Proposed AGC controls active power injected or absorbed by different components such as generation power plant, energy storage, controllable load, so that short term supply–demand balance is maintained. The power flow fluctuation depends on how the AGC control order is dispatched to those control units.

What is IEC 61850 communication model for AGC dispatching scheme?

IEC 61850 communication model for AGC dispatching scheme. Based on these measurements the AGC_Controller calculates the dispatch values for each generator as (2) described in Section 2.

Why do we need a mutually comprehensible language for AGC dispatching?

Not only do they belong to different manufacturers but also different domains, e.g. generators, measurement units and electronic controllers. This requires a mutually comprehensible language. The communication for the proposed AGC dispatching scheme is designed according to IEC 61850.
