⛄ 内容介绍
"双碳"背景下,为提高能源利用率,优化设备的运行灵活性,进一步降低综合能源系统(IES)的碳排放水平,提出一种IES低碳经济运行策略.首先考虑IES参与到碳交易市场,引入阶梯式碳交易机制引导IES控制碳排放;接着细化电转气(P2G)的两阶段运行过程,引入电解槽、甲烷反应器、氢燃料电池(HFC)替换传统的P2G,研究氢能的多方面效益;最后提出热电比可调的热电联产、HFC运行策略,进一步提高IES的低碳性与经济性.基于此,构建以购能成本、碳排放成本、弃风成本最小的低碳经济运行目标,将原问题转化为混合整数线性问题,运用CPLEX商业求解器进行求解,通过设置多个运行情景,对比验证了所提策略的有效性.

function out = addSOSs(cpx, type, ind, wt, varargin)
% Cplex.addSOSs Adds information about a special ordered set
% (SOS) to a problem object of type MILP, MIQP, or MIQCP.
% The problem may already contain SOS information.
%
% Example
% cplex.addSOSs (type, ind, wt, name);
% Add single SOS:
% cplex.addSOSs ('1', [1 2 3]', [1 2 3]', {'sos1(1)'});
% Add set of 2 SOSs:
% cplex.addSOSs ...
% ('12', {[1 2 3]' [4 5 6]'}, {[2 3 4]' [5 6 7]'}, {'s1' 's2'})
% Add SOS structure or structure vector:
% cplex.addSOSs(sos);
% where sos is structure or structure vector with the fields
% type, ind, wt and an optional name.
% See also the example mipex3.m in examples directory
%
% Parameters:
% type char '1' or '2' or string
% SOS type information for the sets to be added.
% ind double column vector or cell vector
% Indices for the sets to be added.
% wt double column vector or cell vector
% Weights for the sets to be added.
% name cell vector
% Names of the new SOSs. Optional.

function out = addQCs(cpx, a, Q, sense, rhs, varargin)
% Cplex.addQCs Adds a quadratic constraint or quadratic constraint
% set to a specified CPLEX problem object.
%
% Example:
% cplex.addQCs(a, Q, sense, rhs, name);
% Add single qc
% cplex.addQCs([0 0 0]',[1 0 0;0 1 0;0 0 1],'L',1,{'qc1'});

% [1 0 0;0 1 0;0 0 1]
% [1 0 0;0 1 0;0 0 1]},
% 'LLG',
% [1.0 2.0 3.0],
% {'qc1' 'qc2' 'qc3'});
% Add qc structure or qc structure vector
% cplex.addQCs(qc);
% qc is structure or structure vector with a, Q, sense,
% rhs,and optional name fields.
%
% See also the example qcpex1.m in examples directory.
%
% Parameters:
% a double column vector or matrix
% Linear part of the quadratic constraint to be added by
% column.
% Q double matrix or cell vector
% Quadratic part of the quadratic constraint to be added.
% sense char 'L' or 'G' or string
% Sense of the constraint to be added. Note that
% quadratic constraints may only be less-than-or-equal-to
% greater-than-or-equal-to constraints.
% rhs double or double row vector
% Righthand side term for the constraint to be added.
% name cell vector
% The name of the constraint to be added. Optional.

function out = addIndicators(cpx, variable, complemented, a, sense, rhs, varargin)
% Cplex.addIndicators Adds indicator constraints to
% the specified problem.
%
% Example:
% cplex.addIndicators(variable, complemented,
% a, sense, rhs, name)
% Add one indicator with a name
% cplex.addIndicators(5, 1,
% [1 2 3 4 5 6]', 'E', 100, {'indc3'});
% Add two indicators with names
% cplex.addIndicators ([5 6], [0 0],
% {[1 1 2 2]' [1 2 3 4 5]'}, 'EE', [10 100],
% {'indc3' 'indc4'});
% Add indicator structure or structure vector
% cplex.addIndicators(indicator);
% where indicator is structure or structure vector which has
% the fields variable, complemented, a, sense, rhs and
% an optional name.
%
% Parameters:
% variable double or vector
% Binary variable that acts as the indicator for this
% constraint.
% complemented double or vector
% Boolean value that specifies whether the indicator
% variable is complemented.
% The linear constraint must be satisfied when the indicator
% takes a value of 1 (one) if the indicator is not
% complemented, and similarly, the linear constraint must be
% satisfied when the indicator takes a value of 0 (zero) if
% the indicator is complemented.
% a double column vector or cell vector
% Linear portion of the indicator constraint.
% sense char 'L','G' or 'E' or string
% Sense of the linear portion of the indicator
% constraint. Specify 'L' for <= or 'G' for >= or 'E' for
% ==.
% rhs double or double row vector
% Righthand side value for the linear portion of the
% indicator constraint.
% name optional parameter cell vector
% Name of the constraint to be added.
% May be empty, in which case the new constraint is assigned a
% default name if the indicator constraints already resident
% in the Cplex problem object have names; otherwise, no name
% is associated with the constraint.
