摘要

为了实现供暖领域煤改电,解决风电消纳问题,引入建筑相变储能系统,提高微网日前调度灵活性与经济性。考虑相变材料变温特性,建立集成于建筑内部的相变储能系统模型,综合考虑室内外扰动量对建筑热平衡的影响,构建以相变储能地板、室内空气以及建筑墙体为主体的建筑精细化热平衡模型。在此基础上,建构以发电成本、购售电成本与弃风成本为总成本,计及建筑热平衡的微网日前调度模型。针对模型中的非线性约束与微分约束,利用分段线性化与差分化,将所提模型转化为混合整数线性规划问题,并通过算例验证所提模型的经济性与有效性。

Abstract

In order to realize the transformation from coal to electricity in the heating field and solve the problem of wind power consumption, building phase change energy storage system is introduced to improve the flexibility and economy of micro grid day ahead scheduling. The model of phase change energy storage system integrated in the building is established by analyzing the temperature change characteristics of phase change energy storage materials. Comprehensively considering indoor and outdoor disturbance factors, a refined building heat balance model with a building phase-change energy storage system for indoor air and building wall is constructed. On this basis, a micro grid day ahead scheduling model is constructed, which takes the power generation cost, power purchasing and selling and wind abandonment cost as the total cost and considers building heat balance. For the nonlinear and differential constraints in the model, the proposed model is transformed into a mixed integer linear programming problem by using piecewise linearization and difference differentiation. An example is given to verify the economy and effectiveness of the model.
