Problems solved by technology

Existing research has focused on the special planning and optimal configuration of a single energy supply system in the power system, and insufficient consideration has been given to the coordinated development and overall benefits of the integrated energy system. The research on system joint planning has just started in recent years. The research focuses more on concepts, ideas and basic theories, and there is still a gap from the actual application of engineering.

Embodiment 1

[0066] The purpose of the present invention is to propose a multi-energy complementary industrial park comprehensive energy station planning and design method, such as figure 1 shown. First, analyze the cooling, heating and power demand of the industrial park, configure energy station equipment according to energy demand, build a multi-energy complementary comprehensive energy station, form a multi-type energy conversion network, and analyze the operation effect. The steps described are as follows:

[0067] Step 1: Use the index method to predict the load in the park;

[0068] 1) Use the index method to forecast the cold, heat and electricity loads in the park.

[0069] Step 1: Use the index method to forecast the cooling and heating loads in the park.

[0070] Calculation of cooling and heating loads is based on the cold index of the building area, namely:

[0071] Q h =q h A c ×10 -3

[0072] In the formula, Q h is the regional cooling and heating load (W), q h is...

Embodiment 2

[0115] The present invention also provides a park comprehensive energy station planning and design system, such as Figure 9 shown. Since the principle of this system to solve technical problems is similar to a planning and design method of a comprehensive energy station in the park, the repetition is no longer redundant. Including: prediction module and structure module;

[0116] The prediction module is used to predict the load in the park by using the index method;

[0117] The structure module is used to determine the energy station structure and equipment capacity in the park according to the prediction results of each load in the park and the resource conditions of the park, while considering the reasonable utilization of equipment;

[0118] The loads include: cooling, heating and electrical loads.

[0119] Preferably, the prediction module includes: a calculation unit, a change unit and a curve unit;

[0120] The calculation unit is used to calculate the cooling and...

Description

technical field [0001] The invention relates to the field of power systems, in particular to a planning and design method and system for a comprehensive energy station in a park. Background technique [0002] Under the dual pressure of energy crisis and environmental pollution, the construction of integrated energy systems (IES) has attracted widespread attention worldwide. Compared with the traditional cooling, heating, and electricity distribution systems, the regional integrated energy system has higher comprehensive energy utilization efficiency and emission reduction value. With the transformation of energy consumption patterns, the traditional single energy supply model is changing to a comprehensive energy supply model, breaking the traditional model of separate planning, separate design and separate operation of different energy varieties. As an energy supply terminal, the energy station plays an important role in the regional energy system, and can realize the coll...
