Problems solved by technology
However, in active distribution network planning, it is necessary to comprehensively consider the influence of controllable loads, adjustable loads, and uncontrollable loads. Therefore, the traditional methods of load forecasting such as single consumption method of output value, trend extrapolation method, and average household capacity method are no longer available. To apply again, it is necessary to comprehensively consider the impact of the above various loads, and study the load forecasting method and planning method suitable for the new load of the active distribution network

The invention provides a load forecasting and planning method for an active distribution network, wherein the forecasting method adopts the load density index method, and the specific steps are as follows: investigate the classification of the load by industry; analyze the data of the planning area; analyze the detailed land use properties in the prospect year; divide Blocks in the planning area in the vision year; determine the load standard in the planning area in the vision year; give the forecast results of load distribution in the planning area in the vision year; give the forecast results of electricity and load in the planning area in the vision year; determine the interruptible agreement and adjustable load pole electric vehicles in the vision year Power station planning indicators; give the distribution of adjustable loads and classification forecasts in the planning area in the long-term year; give the total load and power forecast of the controllable load in the planning area in the long-term year; give the controllable load power and load forecast results in the planning area in the middle year; give The controllable load classification load and classification power forecast results of the planning area in the middle year are obtained; the controllable load distribution prediction results of the planning area in the middle year are given. The prediction method described in the present invention is more accurate, so as to make follow-up planning.
Description
technical field [0001] The invention belongs to the field of active distribution networks, and in particular relates to a load forecasting and planning method for an active distribution network. Background technique [0002] In the 21st century, energy security and environmental protection have become global issues. The Chinese government attaches great importance to the development of renewable energy, and regards it as an important measure to alleviate energy supply contradictions, optimize energy structure, reduce greenhouse gas emissions and respond to climate change, and proposes clear development goals and corresponding incentive policies to encourage the development of new energy. my country advocates the effective combination of the new energy industry and the power industry, and actively carries out research on various aspects of active distribution networks under the condition that the penetration rate of distributed power sources is gradually increasing.
